High blood pressure is considered one of the major risk factors for heart disease. In addition to evidence of low heart disease and death with adequate control of blood pressure, antihypertensive treatment is still less effective in clinical practice. It is well documented that there is a decrease in cardiovascular events, such as stroke and MI, with potent therapies to combat high blood pressure. This, however, is generally believed to be the result of a phase. This review paper includes and focuses on evidence from clinical trials in support of amlodipine as a first-line anti-hypertensive agent, showing how its unique properties can provide better cardiovascular protection compared to other antihypertensive agents to prevent stroke and cardiovascular disease. Evidence from the many randomized controlled trials presented below shows that amlodipine has excellent efficacy and safety, as a first-rate anti-hypertensive agent not only to control BP but also to safely improve patient outcomes. Patients treated with this drug have benefited as they have fewer hospitals and lower rates of recovery. Its unique mechanism of action leads to a reduction in the development of atherosclerosis. In addition, amlodipine with effective BP control for 24 hours may also be helpful as an adjunct to the treatment of patients with renal impairment by reducing the progression of end-stage renal disease.DOI: 10.29245/2578-3025/2021/3.1215 View / Download Pdf

Congenital heart disease, which affects more than one million newborns globally each year, contributes to an increased risk of cardiovascular disease and ultimately reduced life expectancy. Computational fluid dynamics (CFD) enables detailed, non-invasive characterization of complex physiological pressure and flow fields, thus improving our understanding of congenital heart disease hemodynamics.
In recent years, this has driven clinical decision-making, surgical planning, and the evaluation of innovative surgical techniques. In this mini review, CFD methods applied to the study of congenital abnormalities, with a focus on the aorta and pulmonary bifurcation, are discussed. The clinical relevance and future directions of CFD modelling are also reviewed.DOI: 10.29245/2578-3025/2021/2.1213 View / Download Pdf

Background: Cardiac and pericardial metastasis in small cell lung cancer (SCLC) is more common than estimated, but there are a few related studies in the literature. This study aims to raise the attention of such clinical circumstances.
Methods: We analyzed the clinical data of 62 SCLC patients with arrhythmia and confirmed eleven cases of SCLC with cardiac and/or pericardial metastasis by cytology or imaging diagnosis. Survival analysis was performed by the Kaplan-Meier method.
Results: Among 11 patients, 6 had pericardial involvement, 10 had mediastinal lymph node metastasis, and 8 had hilar lymph node metastasis. The most common type of electrocardiogram (ECG) abnormality was supraventricular arrhythmias (10/11). Complete imaging data were obtained in 7 patients through whole treatment after diagnosed with cardiac metastasis. Among them, 5 patients achieved partial response, and 2 of them achieved improvements in ECG abnormality. In the two remaining patients, advances in imaging diagnosis were identified after treatment, and new abnormalities were found in their ECG. The median overall survival time of the 11 patients was 11 months.
Conclusions: Cardiac and pericardial metastasis of SCLC can present different types of arrhythmia, and the ECG may change after treatment. Clinicians should take this condition into consideration, and aggressive treatment may achieve significant remission.DOI: 10.29245/2578-3025/2021/1.1211 View / Download Pdf

Background: Survival after myocardial infarction (MI) is improving leading to increasing numbers of people dealing with heart health recovery, readjustment and re-investment in their future wellbeing and that of their family. Cardiac Rehabilitation (CR) aims to improve outcome by ensuring patients adopt recommended health maintenance strategies. This study explored the health maintenance needs of adults one to three years after an MI. The theoretical framework guiding the study was Leventhal’s Self Regulation Model. Data from the completion of different measures of health and illness representation are presented and the potential for measuring current health status and their explanatory factors is illuminated.
Aims: To identify the longer-term health needs of adults who have suffered an acute MI.
Methods: A mixed method design was used to explore respondents’ illness representations and the factors believed to be impacting on their longer-term health and health behaviour. A sample of 73 adults completed 3 questionnaires to assess their illness perceptions, mood and quality of life (QoL) 1 to 3 years after discharge from hospital. A sub-sample (n=30) participated in an interview, underwent a brief clinical assessment, and completed a small task. Data analysis used StatsDirect and Nudist 5.
Results: One to three years post-discharge, Personal and Treatment control belief scores of 22.6 ± 4.3 and 17.6 ± 4.3 respectively were strong, but perceived consequences high (20.6 ± 4.9). Many respondents were experiencing low energy (92%), breathlessness (67%) and chest pain (53%), and many reported a sense of loss that affected their ability to sustain health and positive health behaviour. Those with the poorest attendance at CR had poorer QoL, anxiety, and depression scores, and women had poorer outcomes than men in many of the indices assessed (p<0.05). Initial compliance with prescribed drug regimens and lifestyle recommendations (self-report) was not maintained.
Conclusion: This preliminary study supports the notion that there is a largely unmet and persistent health need among adults diagnosed with MI, and that more consideration needs to be paid to its longer-term effects and the needs of women. Combining surveys with interview methods and tools such as the PRISM+ provide an opportunity to understand the complexity of patients’ health evaluation.DOI: 10.29245/2578-3025/2020/4.1205 View / Download Pdf

Peripartum cardiomyopathy is a idiopathy cardiomyopathy associated with heart failure towards the end of pregnancy or in the postpartum period. Various mechanisms like myocarditis, autoimmune response to pregnancy, viral infections, selenium deficiency, oxidative stress and prolonged tocolysis have been proposed as the etiology. The most common presentation is acute heart failure occurring usually within a few weeks after delivery with patients developing exertional breathlessness, orthopnea and paroxysmal nocturnal dyspnea. Cardiac Magnetic Resonance Imaging is useful in accurate measurement of chamber volumes and global and segmental myocardial function. The gold standard test for diagnosis of peripartum cardiomyopathy is Endomyocardial biopsy with the histological Dallas criteria. Most of these postpartum patients are managed medically. The risk of peripartum cardiomyopathy increases with increasing parity and outcomes in subsequent pregnancies was poor.DOI: 10.29245/2578-3025/2020/4.1204 View / Download Pdf

One of the most important causes of death in Western society, following cancer, is myocardial infarction (MI). Although acute MI occurs at an older age, the incidence of acute MI in younger adults has increased.
Essentially, treatment of acute MI is reperfusion therapy, which should preferably be performed within 12 hours of onset of the symptoms. Time is imperative and shorter intervals between symptoms an reperfusion leads to lower mortality. Conversely, a longer interval results in higher mortality, more mechanical complications and morbidity.
At our institution, located in the middle of a thinly populated rural area, patients used to be treated with thrombolysis until 2005. The nearest centers for percutaneous coronary interventions (PCI) and cardiothoracic surgery, had a travelling distance of 60 minutes. Since the introduction of interventional cardiology in the province of Drenthe, we managed to reduce the symptom to needle time.
Recently, we have been confronted with the COVID-19 pandemic, led to an increase in patient’s and doctor’s delay. This unfolded new challenges in treating acute MI.
This overview addresses the general clinical approach of acute MI and highlights the diagnostic approach and treatment options of both premature atherosclerosis and non-atherosclerotic causes of MI from our clinical perspective. We would like to argue that a personalized clinical approach remains of utmost importance in each patient treated by protocolized medicine.DOI: 10.29245/2578-3025/2020/2.1200 View / Download Pdf

The presence of coronary calcification is a hard challenge for the interventional cardiologist, as it is associated with incomplete stent expansion and frequently stent failure. In recent years, innovative techniques have been developed to treat coronary calcific lesions such as rotational atherectomy. However, many of them are burdened with an increased procedural risk. Recently, a new technique called “Shockwave Coronary Lithoplasty System”, also called lithotripsy, has been introduced in order to treat calcific coronary lesions with greater safety. Shockwave procedure allows treating the most calcific coronary lesions with simplicity and safety. This system employs the sound waves, similar to that used for treating kidney stones, in order to crush the calcific lesions. In this minireview, we explain the characteristics of the method and we provide a description of the technique in detail on the basis of the preliminary experience of the first cases. In particular, we will demonstrate that this technique is more effective and safer than traditional techniques employing atherectomy, also providing for the first time a therapeutic chance for the treatment of under-expanded stents in many clinical contexts.DOI: 10.29245/2578-3025/2020/3.1202 View / Download Pdf

In the human heart, the action potential (AP) is initiated and maintained thanks to a fast-activating fast-inactivating Na+ current carried by Nav1.5 channels. The pivotal physiological role of Nav1.5 in the heart is reflected by the important consequences of its coding SCN5A gene mutations. These mutations may lead to an impaired functional expression (including expression level, subcellular localization, trafficking, and/or current density), and are generally correlated with severe cardiac rhythm disorders such as Long QT (LQT) and Brugada syndrome (BrS). In BrS, loss of function mutations in SCN5A account for 35-40% of clinically affected patients and around 400 mutations in the SCN5A gene were identified in probands with BrS. Emerging electrophysiological techniques such as patch clamp along with transgenic animal technologies improved our understanding of the pathogenic mechanisms underlying BrS due to SCN5A variants. However, despite significant advances in defining the pathophysiology of Nav1.5, the molecular mechanisms underlying its regulation and contribution to the disease are poorly understood. It is well established that functional expression of Nav1.5 may be under modulation by post-transcriptional regulators, defining thus its transcript levels in the cell and also the penetrance on its associated diseases. Recently, non-coding RNA (ncRNAs) molecules have been identified as key transcriptional regulators of SCN5A expression in the heart. The present mini-review provides a summary of the role of ncRNAs, especially microRNAs (miRNAs), in the regulation of SCN5A. It mainly focuses on their role in the BrS context and discusses the recent updates and the major gaps still to be elucidated.

Noncompaction cardiomyopathy is a heterogeneous and complex entity characterized by hypertrabeculation, typically of the left ventricle. Uncertainties regarding pathogenesis, classification as primary genetic or unclassified cardiomyopathy, diagnostic criteria, and risk stratification have contributed to fuel the discussion surrounding this disorder. Meanwhile, noncompaction phenotype is thought to be the morphological expression of different underlying pathophysiological mechanisms, genetics, and pathologies. Recent studies suggest that distinguishing genetic from nongenetic causes allows risk stratification and may support clinical management and counselling of patients and their relatives. Additionally, advanced cardiac imaging techniques have demonstrated a complementary role in outcome prediction. The purpose of this review is to provide a brief comprehensive review of this controversial entity.DOI: 10.29245/2578-3025/2020/2.1198 View / Download Pdf

Atrial Fibrillation (AF) is associated with an increased risk of thromboembolism due to formation of intracardiac thrombus mostly in left atrial appendage. Anticoagulant agents are used to reduce the risk of thromboembolism but have concerning bleeding side effect, making their use very challenging particularly in patients with high HAS-BLED risk score. WATCHMAN device (Boston Scientific, St. Paul, Minnesota) is a Left Atrial Appendage Occlusion (LAAO) device, which was tested in two major randomized trials. PROTECT AF (Percutaneous Left Atrial Appendage Closure for Stroke Prophylaxis in Patients with Atrial Fibrillation) trial, and PREVAIL (Prospective Randomized Evaluation of the WATCHMAN Left Atrial Appendage Closure Device in Patients with Atrial Fibrillation versus Long Term warfarin Therapy) trial, both evaluated WATCHMAN device’s safety and efficacy compared to warfarin. These trials showed WATCHMAN device to be non-inferior to warfarin. However, patients with history of intracranial hemorrhage were excluded from these trials due to concern of increased recurrent bleeding in presence of perioperative use of anticoagulation. Purpose of this review is to evaluate existing evidence and share our experience of LAAO in this high-risk population.DOI: 10.29245/2578-3025/2020/2.1197 View / Download Pdf

Among different sources that contribute in the global oxidative stress, the vast majority of cellular reactive oxygen species (ROS) originate from mitochondrial compartments. Recently, monoamine oxidases (MAOs) are identified as a prominent source of ROS. Monoamine oxidases are localized in the outer membrane of mitochondria and exist as two different isoforms, MAO-A and MAO-B. MAOs are mitochondrial flavoenzymes responsible for oxidative deamination of biogenic amines and during this process, H2O2 and aldehydes are generated as intermediate products. The role of monoamine oxidase in cardiovascular pathophysiology has only recently gained some attention as it is demonstrated that H2O2 and aldehydes may target myocardial function and consequently cardiac function. Results obtained by different research groups showed that MAO-A plays a key role in the regulation of physiological cardiac function and in the development of acute and chronic heart diseases through two mechanisms: regulation of substrate concentration and intracellular production of ROS. In this review, we will focus on the role of MAO-A in the field of cardiac aging and related diseases.

Background: Coronary artery bypass grafting (CABG) is a major surgical intervention to relieve symptoms and promote survival for individuals with coronary heart disease (CHD). The benefits of the intervention are thought to be improved when underlying risk factors of CHD are ameliorated. However in current health care systems the long-term follow-up of patients following CABG is not centralized to allow for the determination of survival trends and their optimization. The survival of study participants who underwent CABG is compared with age and gender matched individuals from the general population. Differences in rates of survival are interpreted in terms of lifestyle choices and the impact of risk factors of CHD.
Method: Survival data were obtained from government records to 18 years post intervention on a cohort of patients underwent CABG and participated in a long-term follow-up program. Cardiac symptoms and risk factors of CHD were collected from consenting participants (44 women and 164 men) prior to CABG and at clinical assessments at one and eight-year follow-ups. Important clinical and lifestyle factors were identified and their impact on post-operative survival was quantified using a maximum likelihood technique. Male and female patients were investigated separately and a good fit between observed and simulated survival experiences was confirmed by Monte Carlo simulation.
Results: Cardiac symptoms were exhibited by 75.8% of women and 68.3% of men (χ2=0.712, p=0.3988) one-year post operation, and by 84.2% of women and 70.2% of men eight-years post operation (χ2=1.556, p=0.212). Male long-term survival at 54.3% after 18 years was significantly better than 36.4% for females (χ2=4.449, p=0.035), but both were worse than 73.0% and 71.5% (p=0.6114) respectively for gender and age-matched cohorts from the general population.
Important risk factors for women were post-operative smoking and post-operative hypertension reducing annual post-operative survival by 3.9% and 2.7% respectively and by 6.6% when both present. Equivalent important risk factors for men are post-operative smoking and unrelieved/recurring cardiac symptoms reducing annual survival rates by 2.4% and 1.2% respectively and by 3.6% when both present.
Conclusion: Eighteen year survival post CABG was significantly better for men than women, but both were worse than that for the general population. Post-operative smoking was the most significant risk factor associated with decreased rates of survival followed by unrelieved/recurring cardiac symptoms for men and persisting hypertension for women.DOI: 10.29245/2578-3025/2020/2.1193 View / Download Pdf

Enhanced Recovery After Surgery (ERAS) incorporates multi-modal interventions that synergistically improve patient outcome. Its goals include improving patients functionally pre-operatively, reducing the stress of surgery intra-operatively to facilitate early return to daily activities. We conducted a pilot study at our unit recruiting patients undergoing elective coronary artery bypass grafting (CABG) into the Cardiac ERAS (C-ERAS) pilot and compared them with the patients undergoing CABG meeting the ERAS criteria but who not included the C-ERAS pilot (Control).
Materials and Methods: 122 C-ERAS patients were compared to 91 control patients who underwent CABG only from the period of July 2015 to September 2016. All C-ERAS patients received pre-operative counselling by a dedicated ERAS Practitioner to manage expectations of the patient journey, health promotion and pre-operative optimisation advice. Emphasis was made on educating the patient on daily goals for recovery and patients were followed up daily by the ERAS practitioner post-operatively.
Results: There were 122 patients in the C-ERAS group and 91 patients in the control group. The mean age was 63.6±9.9 years. 181(85%) of the patients were males. After adjusting for the abovementioned confounders, C-ERAS patients had a shorter length of stay that was statistically significant. (2.36 days shorter (95% CI; 1.01-3.7 days; p<0.01). The difference in mean bed day costs was £1153.70 (95% CI, £553.70-£1753.7; p<0.01) less in the C-ERAS cohort.
Conclusion: This study highlighted that C-ERAS is a safe and feasible pathway to reduce in-hospital stay with no difference in complications and readmission rates compared to routine management of patients. There was also a significant cost saving with the C-ERAS pathway mimicking the results in enhanced recovery programmes in the other surgical specialities.

The clinical presentation of cardiac sarcoidosis (CS) ranges from an incidentally discovered condition to heart failure and sudden death. The diagnosis of CS is tough, and as a result, CS is often under-recognized in clinical practice. CS is mostly noted in the setting of systemic sarcoidosis, though isolated CS can occur. Frequently clinical criteria require the diagnosis of extracardiac disease in order to establish the diagnosis of CS in the absence of having a positive endomyocardial biopsy. While endomyocardial biopsy provides a high specificity for diagnosing CS, this invasive test has a limited sensitivity. There is incomplete knowledge of disease development and a deficient consensus on the ideal methods for disease recognition. We discuss CS in general, the clinical disease, diagnostic algorithms, latest guidelines and management.

The leisure intake of cannabis has shortly amplified in the past years corresponding with its decriminalization and legalization. The natural cannabis has been substituted by synthetic cannabinoids and cannabimimetic in several formulae, which are stronger. In spite of irresistible public insight into the safety of these substances, a growing quantity of grave cardiovascular adverse events are reported in sequential relation to recreational cannabis intake. A multifaceted interface between the active ingredients, the endo-cannabinoid system, and the autonomic nervous system is responsible in the pathophysiology. Tolerance to the properties of cannabis can develop with repetitive contact due to receptor desensitization. Effects of cannabis may be heightened or transformed by affiliated use of other illicit drugs or drug treatment indicated for the treatment of cardiovascular diseases. Nonetheless, the recent cannabis epidemic would significantly increase global burden of cardiovascular diseases.DOI: 10.29245/2578-3025/2020/2.1195 View / Download Pdf

Readmission for Acute Myocardial Infarction [AMI] significantly contributes to preventable morbidity and healthcare costs. Nearly 1 in 6 patients hospitalized with AMI have an unplanned readmission within 30 days of discharge, accounting for over $1 billion of annual US healthcare costs. We developed a unique integrated product in our hospital called “Transition of Care” program [TOC] with the help of technology and services from Patient Engagement Advisors. The TOC program was based on the notion that engaging patients in their self-care journey by provision of extended set of products and facilities, nutrition, medications, and services to meet their care and recovery needs across the continuum of care.
The TOC program led to the subsequent reduction in the AMI readmission and significant cost savings by avoiding Medicare penalties. AMI readmission rates were reduced to less than 20% since implementation and have fallen below expected rates. This has translated to more than $ 400,000 savings in penalties as the actual readmission rate has been under the expected rate.
It also led to improved clinical follow up in the post AMI patients and improvement in clinical parameters in patients with chronic conditions like diabetes and hypertension. The TOC program extends health care beyond the four walls of the medical care facility and never truly discharges the patient.

Vaccination against atherosclerosis as a potential effective approach has been under investigation for more than 20 years. Different antigens have been tested in animals with a great success. Lipid-related antigens like Ox-LDL, PCSK9, non-lipid related antigens like interleukins, HSPs β2GPI, DNA vaccination and whole cell vaccination are some examples of successful examinations in animals. Plant-based vaccination which has some advantages over traditional methods has been attracted the scientists´ attention recently. Despite the very substantial struggles and promising results during these years, vaccination against atherosclerosis could not be utilized for the treatment of atherosclerosis in human in part due to the lack of clinical trials to access its safety and efficacy. In fact, designing clinical trials with a sufficient number of participants together with a sufficient duration of follow up to explore the influence of vaccine on the prevention and treatment of atherosclerosis seems to be an imperative requisiteness. It looks investing on clinical trials must be a priority to achieve a clear sight regarding the new, tempting, and promising strategy for vaccination against atherosclerosis.DOI: 10.29245/2578-3025/2020/1.1190 View / Download Pdf

There is growing recognition of the importance and multiple roles of substrate energy metabolism in both cardiac health and disease. Cardiac diseases are frequently accompanied by altered myocardial metabolism, while chronic changes in the type of myocardial substrate utilization are found to elicit cardiac contractile dysfunction. Examples are the increased glucose utilization, at the expense of fatty acids, in cardiac hypertrophy and ischemic heart failure, and the increased fatty acid utilization, at the expense of glucose, in obesity and diabetes-related cardiac dysfunction. Modulation of cardiac metabolism has emerged as a suitable therapeutic intervention in cardiac disease. Insights obtained during the past decade have revealed sarcolemmal substrate transport, facilitated by CD36 for fatty acids and by GLUT4 for glucose, to represent the main rate-governing kinetic step of substrate utilization, over-ruling intracellular sites of flux regulation. This suggests that manipulating the presence of substrate transporters in the sarcolemma may be an effective approach for metabolic modulation therapy. The present mini-review provides a short summary of the functioning of substrate transporters CD36 and GLUT4 in the heart, and discusses their application as targets for metabolic intervention.

Falciparum malaria has a unique and complex pathophysiology. While sequestration of parasitized and non-parasitized erythrocytes leads to a progressive obstruction of the microcirculation, a marked systemic inflammation with endothelial dysfunction and consecutive increase in vascular permeability develops. Furthermore, most patients with severe disease present with some degree of hypovolemia. Due to the reduction in pre-load, direct myocardial suppression and increase in after-load acute falciparum malaria exerts diverse effects on the cardiovascular system. Increasing numbers of aging tourists and immigrants with chronic co-morbidities travel to countries where falciparum malaria is endemic. Age has consistently been described as a prominent risk factor for both severe disease and death from imported falciparum malaria in several large studies. Although for long suspected age-related chronic disorders have only recently been identified as risk factors for severe disease. Herein, we review the current concepts of the impact of age-related chronic medical conditions on the severity of imported falciparum malaria.DOI: 10.29245/2578-3025/2020/1.1188 View / Download Pdf

Hypertension is a key risk factor for cardiovascular disease. Globally, approximately a third of people with hypertension remain undiagnosed, and of those diagnosed, about half are not taking antihypertensive medication. The World Health Organization has estimated that globally hypertension directly or indirectly causes the deaths of at least nine million people every year.
There is a trend towards self-monitoring of blood pressure (BP), where patients are empowered to be involved in hypertension screening and diagnosis. Novel technology, including smartphones and Blue-tooth® enabled telemonitoring, are new tools that are likely to be increasingly important in hypertension management. Several studies have shown the benefit of self-monitoring of BP coupled with co-interventions (such as telemonitoring) in improving BP management. However, these new technologies must be properly assessed and clinically validated prior to widespread implementation in the general population, or within special groups. In this mini-review, we examine how technology might improve the detection and management of hypertension.DOI: 10.29245/2578-3025/2020/1.1186 View / Download Pdf

Intravenous immunoglobulins (IVIGs) are immunomodulating agents prepared using pooled plasma from thousands of human donors. These IVIGs have been used to treat a wide range of autoimmune, infectious, and idiopathic diseases. Their use in idiopathic thrombocytopenic purpura (ITP) was first described in 1981 and was found to be an effective alternative to splenectomy. The standard dose of IVIG in patients with ITP is 400 milligrams per kilogram body weight (mg/kg) daily for 5 days however recent data has shown a dose of 1 gram/kilogram/day for 2 days may be more effective. Side-effects during IVIG infusions have been reported in about 5 to 15% of patients. Cardiac related side-effects such as arrythmias, hypotension, and even myocardial infarction, being rare, have also been documented but are usually seen in patients with underlying cardiac pathologies. This article presents a 61-year-old male with no history of cardiac disease or arrhythmias who developed symptomatic bradycardia thirty minutes after intravenous immunoglobin infusion requiring multiple atropine injections and dopamine infusion over a 7-day hospitalization. The bradycardia resolved afterwards, and cardiac workup did not identify any underlying pathology.DOI: 10.29245/2578-3025/2020/1.1185 View / Download Pdf
