Original Article--Value of Pathological Q Waves and Angiographic Collateral Grade in Patients Undergoing Coronary Chronic Total Occlusion Recanalization: Cardiac Magnetic Resonance Study.

Background/aim: Successful coronary chronic total occlusion (CTO) revascularization was found by many studies to be associated with improved left ventricular (LV) systolic function and survival if evidence of viability is present. Little is known about the association of CTO revascularization in patients with electrocardiographic Q waves and improvement in angina burden as a measurement of health-related quality of life (HRQOL) afterwards.

Methods: In this study, 100 patients with single vessel CTO were included.

Relationship between quality of coronary collateral and myocardial viability in chronic total occlusion: a magnetic resonance study.

Revascularization of chronic total occlusion (CTO) is still debated regarding its indications and therapeutic benefits. Guidelines recommend patient selection based on ischemia detection and viability assessment. We aimed to investigate the relationship between the quality of coronary collaterals (CC), graded by Rentrop classification, and myocardial viability assessed by cardiovascular magnetic resonance (CMR).

Relationship between sclerostin and coronary tortuosity in postmenopausal females with non-obstructive coronary artery disease.

Background: Coronary tortuosity (CT) is commonly encountered in postmenopausal females and is usually present without obstructive lesions. Circulating sclerostin levels are elevated in postmenopausal females. In view of sclerostin's vasculoprotective effect, we aimed to find possible association between circulating sclerostin and CT.

Echocardiographic parameters differentiating heart failure with preserved ejection fraction from asymptomatic left ventricular diastolic dysfunction.

Background: (LVDD) either remains latent or manifests as heart failure with preserved ejection fraction (HFpEF). Little is known about echocardiographic parameters associated with symptomatic phenotype.

Objective: To investigate echocardiographic parameters associated with symptomatic state in LVDD.

Tissue Doppler-derived atrial dyssynchrony predicts new-onset atrial fibrillation during hospitalization for ST-elevation myocardial infarction.

Background: Atrial dyssynchrony, but not atrial enlargement/dysfunction, reflects acute atrial histopathological changes. It has been shown to be associated with new-onset atrial fibrillation (NOAF) in various clinical conditions but was not studied in the acute phase of ST-elevation myocardial infarction (STEMI) which is the aim of the current study.

Methods: A total of 440 STEMI patients underwent primary percutaneous coronary intervention (PCI) and were monitored for NOAF during hospitalization.
