PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

Introduction: Atrial fibrillation (AF) is the most common form of cardiac arrhythmia in clinical practice and its prevalence increases with age. Patients who develop AF also have cardiovascular risk factors, structural heart disease, and comorbidities, all of which can increase mortality. AF causes a significant economic burden with the increasing trend in AF prevalence and hospitalizations. Research Objectives: The objective of our study is to evaluate the impact of the most common known risk factors on the incidence of atrial fibrillation as an important precursor of cardiac and cerebrovascular morbidity and mortality among our patients in Bosnia and Herzegovina during median follow up period (September 2006 - September 2016)...

Endocardial endothelium (EE) is essential in the embryonic development of the heart, the optimal contractility and rhythm as well as the remodeling of the heart. Endocardial endothelium affect the contractility of cardiomyocytes through paracrine signaling substances such as nitric oxide (NO), endothelin (ET-1), prostaglandins (PGI2, PGF2, PGE2) and angiotensin II (ANG II). Typical lesions of endocardial endothelium have been described in atrial fibrillation, ischemia/reperfusion injury, cardiac hypertrophy, heart failure, sepsis, myocardial infarction, inflammation and thrombosis...

The American College of Cardiology/American Heart Association guidelines include a Class 1 recommendation to initiate therapeutic hypothermia (TH) in comatose patients with out-of-hospital cardiac arrest (OHCA) with an initial shockable rhythm who have achieved return of spontaneous circulation. There is also a Class 1 recommendation for immediate angiography in these patients whose initial electrocardiography shows ST-elevation myocardial infarction (STEMI). However, due to a lack of clinical trials evaluating these patients who have received both percutaneous coronary intervention (PCI) and TH, controversy remains regarding whether the two can be safely combined...

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia affecting patients in open heart ICU after coronary artery bypass grafting (CABG). Most cardiac surgery textbooks recommend beta blockers as the drug of choice for treating such a condition while many experienced physicians and a number of anesthesiology references offer amiodarone as the drug of choice. Therefore, because of insufficient evidence and the aforementioned controversy, we decided to conduct a study evaluating these two antiarrhythmic medicines...

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e...
