A 64-year-old woman presented for chest pain and was diagnosed with anteroseptal ST segment elevation myocardial infarction (STEMI). Emergent angiography showed 95% stenosis at the ostium of the second septal branch, consistent with thrombus, and no other significant lesions. The lesion was not amenable to intervention due to small caliber.

It is a common complication after percutaneous coronary intervention, especially in patients with acute coronary syndrome (ACS). The aim of this study is to determine the utility of red cell distribution width (RDW) in predicting CI-AKI in patients with ACS and to determine the value of adding RDW to the Mehran risk score (MRS) on admission.

Reverse takotsubo cardiomyopathy is an uncommon cardiomyopathy characterized by reversible regional wall motion abnormalities in the basilar segment of the left ventricle. This happens in the absence of any coronary artery pathology. Although it shares some pathogenic mechanisms with its more common variant, takotsubo cardiomyopathy, differences exist in terms of echocardiographic features, demographics, clinical manifestations, laboratory features, and prognosis.

Background: Angiographers base decisions to perform FFR on their interpretation of % diameter stenosis (DS), which is subject to variability. Recent studies have shown that the amount of myocardium at jeopardy is an important factor in determining the degree of hemodynamic compromise.
Background: Waterpipe smoking is becoming a popular way of tobacco use in the world. Its acute effects on the cardiovascular system are not well investigated.
Materials And Methods: This is a trial designed to evaluate the acute effects of waterpipe smoking on blood pressure (BP) and heart rate (HR) in healthy adults.
We describe a 41-year-old man with De Mosier's syndrome who presented with exercise intolerance and dyspnea on exertion caused by a giant hiatal hernia compressing the heart with relief by surgical treatment.

Plaque rupture with superimposed thrombosis is the major mechanism of acute coronary syndromes. Although angiography underestimates the presence of thrombi, their detection is a poor prognostic indicator which is proportional to their size. Although emergent percutaneous coronary intervention (PCI) in the setting of ST elevation myocardial infarction (STEMI) and early PCI in the setting of unstable angina and non-STEMI were shown to be preferred strategies, the presence of angiographic thrombosis by virtue of causing micro and macro embolization can reduce the benefit of the intervention.
