Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was the main pathogen in the COVID-19 pandemic. This viral infection has been associated with several respiratory and non-respiratory complications contributing to a higher mortality rate, especially in patients with underlying heart diseases worldwide. Once considered a respiratory tract disease, it is now well-known that COVID-19 patients may experience a wide range of cardiac manifestations. Because of its remarkable direct and indirect effects on the cardiovascular system, herein, we examined the published literature that studied the hypothetical mechanisms of injury, manifestations, and diagnostic modalities, including changes in molecular biomarkers with a predictive value in the prognostication of the disease, as well as emerging evidence regarding the long-term cardiac complications of the disease...

Background: In patients with ST-segment-elevation myocardial infarction (STEMI), it is essential to determine the complexity of coronary lesions on presentation and predict the risk of no-reflow after primary percutaneous coronary intervention (pPCI). Given that inflammation plays an important role in the pathogenesis of atherosclerosis, using inflammatory indices might be helpful in this setting. Methods: This prospective cohort study recruited 200 consecutive patients with STEMI who underwent pPCI. The presentation neutrophil-to-lymphocyte-ratio (NLR) and the systemic inflammatory immunologic index (SII), calculated using the formula platelets × neutrophils/lymphocytes, were recorded...

OBJECTIVE: Using the α1-adrenergic agonist phenylephrine (PE), we have previously demonstrated that an acute episode of transient pressure overload (TPO) elicits stretch-induced myocardial injury and reversible left ventricular (LV) systolic dysfunction. Although this was accompanied by leukocyte mobilization, a rise in inflammatory cytokine levels, and increased pro-inflammatory gene expression in the heart, the extent to which this resulted from direct activation of α1-adrenergic receptors on immune cells vs...

OBJECTIVE: Diagnosis of heart failure with preserved ejection fraction (HFpEF) is often complicated by the fact that many patients exhibit normal left ventricular (LV) mechanics at rest with a reduction in diastolic compliance that is only revealed when loading conditions are altered (e.g., during exercise stress). In an effort to identify parameters of diastolic function that could be utilized to detect alterations in compliance without manipulation of LV loading conditions, we utilized invasive hemodynamic analysis and speckle-tracking echocardiography (STE) to assess diastolic strain and stiffness in swine with repetitive pressure overload (RPO)-induced HFpEF...

Introduction: Considering the role of inflammation in pathogenesis of atherosclerosis, we aimed to investigate the association of presentation neutrophil to lymphocyte ratio (NLR) with complexity of coronary artery lesions determined by SYNTAX score in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). Methods: From March 2018 to March 2019, we recruited 202 consecutive patients, who were hospitalized for NSTE-ACS and had undergone percutaneous coronary intervention in our hospital. The association of presentation NLR with SYNTAX score was determined in univariate and multivariate linear regression analysis...

Introduction: The knowledge regarding the demographic characteristics of patients with Covid-19 and risk factors distribution is still evolving. Considering the role of cigarette smoking in the pathogenesis of lung diseases and the effect of nicotine on expression of the entry receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is important to determine the implications of smoking in COVID-19. Methods: In this brief report, by using the published articles in the literature, we aimed to compare the reported prevalence of smoking in patients with COVID-19 to the prevalence of smoking in the general population of the corresponding report...

PURPOSE: ST depression resolution (STD-R) in ECG is a prognostic factor indicative of successful fibrinolysis or angioplasty in the treatment of ST elevation myocardial infarction (STEMI) and subsequent mortality. We conducted this study to determine the clinical significance of STD-R and its predictors in patients with anterior STEMI undergoing primary percutaneous intervention (PPCI). METHODS: Admission documents of all patients with diagnosis of anterior STEMI who were admitted to a specialty heart center and underwent PPCI since July 2018 until July 2019 were examined...

Introduction: Given the role of platelets in thrombus formation, markers of platelet activation may be able to predict outcomes in patients with acute pulmonary thromboembolism (PTE). Methods: In a prospective cohort study, 492 patients with acute PTE were enrolled. Patients were evaluated for platelet indices including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-lymphocyte-ratio (PLR), as well as for the simplified Pulmonary Embolism Severity Index (PESI) risk score. The primary endpoint was in-hospital all-cause mortality...

BACKGROUND: Epicardial adipose tissue (ECAT) is metabolically active and is involved in the development of atherosclerosis. The thickness of ECAT has been positively correlated with the dimensions of the ascending aorta. We aimed to examine whether ECAT thickness predicted the expansion of the aortic dimensions. METHODS: The imaging results of patients who had undergone transthoracic echocardiographic (TTE) examinations more than twice during the period 2005-2015 were surveyed...

Acute heart failure (AHF) is a complex disorder involving different pathophysiological pathways. In recent years, there is an increased focus on biomarkers that help with diagnosis, risk stratification and disease monitoring of AHF. Finding a reliable set of biomarkers not only improves morbidity and mortality but it can also potentially reveal the new targets of therapy. In this paper, we have reviewed the biomarkers found useful for the diagnosis as well as for risk stratification and prognostication in patients with AHF...

Introduction: Smoking, which is a major modifiable risk factor for coronary artery diseases, affects cardiovascular system with different mechanisms. We designed this study to investigate the association of smoking with location of ST-segment elevation myocardial infarction (STEMI), and short-term outcomes during hospitalization. Methods: In 1017 consecutive patients with anterior/inferior STEMI, comprehensive demographic, biochemical data, as well as clinical complications and mortality rate, were recorded...

Introduction: Stress echocardiography is a safe and cost-effective method of evaluating the patients with suspected coronary artery disease (CAD). However, the risk factors of an adverse cardiovascular event after a normal exercise (ESE) or dobutamine (DSE) stress echocardiography are not well established. Methods: A cohort of 705 patients without previous history of CAD and a negative ESE/DSE was studied. All studies were performed in a high-volume echocardiologic laboratory and interpreted by two experienced echocardiography-trained cardiologists...
