Introduction: Little is known about discrepancies between patients who present with or without STEMI following out-of-hospital cardiac arrest (OHCA). Material and Methods: All patients with OHCA who were admitted to our hospital between January 1st 2008 and December 31st 2013 were classified according to their initial laboratory and electrocardiographic findings into STEMI, NSTEMI or no ACS. Re...

INTRODUCTION Myocardial bridging (MB) is a congenital variant of the coronary artery in which a portion of the epicardial coronary artery takes an intramuscular course. Although it is considered a benign anomaly, it may lead to such complications as myocardial ischaemia, acute coronary syndrome, coronary spasm, exercise-induced dysrhythmias or even sudden death. MB may be related to increased i...

background: streptokinase, which is injected intravenously with a standard dose of 1.5 miu, is the most widely used thrombolytic agent around the world. what is so important about this bioproduct is the level of antistreptokinase (anti-sk) antibody in the population, which is directly correlated to the incidence of streptococcal infections in that population. objective: since iran is an endemic...

OBJECTIVE To determine the safety and success of transradial coronary angiography and angioplasty in a Pakistani population. METHODS This was a prospective study on 264 consecutive patients undergoing transradial coronary angiography (TRCAG) and angioplasty (TRCAP) at Tabba Heart Institute, Karachi between November to December 2008. All patients enrolled in the study underwent Allen's test to...

INTRODUCTION Coronary slow flow (CSF) is an angiographic phenomenon characterised by the delay of distal vessel opacification in the absence of significant stenosis of the epicardial coronary arteries. Some of the factors playing a role in CSF pathophysiology are increased thrombogenic activity and inflammation. AIM To examine the relationship between platelet distribution width (PDW) and CSF...

BACKGROUND The aim of this study was to examine the trend in increasing life expectancy in relation to heart attack and cardiac catheterization. METHODS A retrospective study of very elderly patients over 90 years of age (study group) and between 70 and 79 years of age (control group) with myocardial infarction and acute coronary syndrome who underwent coronary angiography was conducted. RE...

Aneurysmal coronary disease or ectasia is defined as the dilation of a vessel at least 1.5 times the diameter of a normal adjacent segment. The prevalence of the disease has been encountered in up to 5% of patients undergoing angiographies. Atherosclerotic heart disease has been mentioned as the most common etiologic factor involved in the development of coronary aneurysms. We present a case of...

Chronic total coronary occlusions (CTO) are documented in approximately one fifth of diagnostic invasive coronary angiographies (ICA). Percutaneous coronary interventions (PCI) of CTO are challenging and are accompanied by higher complication and lower success rates in comparison with non-CTO PCI. Scrutinous evaluation of ischemia and viability to justify percutaneous revascularization is there...

OBJECTIVES The MESA (Multi-Ethnic Study of Atherosclerosis) is a population-based study of 6,814 men and women. We sought to analyze the relationship between the extent of coronary artery calcium (CAC) at baseline and the severity of coronary stenoses in clinically indicated coronary angiography studies during follow-up. BACKGROUND CAC is an established predictor of major cardiovascular event...

BACKGROUND The aim of our study is to determine the incidence of single coronary artery (SCA). SCA is a rarely seen coronary anomaly in which the right coronary artery and the left main coronary artery arise from single aortic sinus. Although SCA has a benign course in most cases and its clinical significance is unknown, in some autopsy studies it was shown to be related to sudden cardiac death...
