Myocardial tissue perfusion predicts the evolution of fragmented QRS in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Background: Fragmented QRS complex (fQRS) is associated with worse outcomes in several cardiovascular conditions. However, alterations in fQRS in patients with ST elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and association of fQRS with myocardial blush grade (MBG) has not been investigated until now. In this study, we aimed to investigate the association of MBG after primary PCI with evolution of fQRS.

The effect of different circadian blood pressure rhythms on left ventricular systolic dyssynchrony in patients with newly diagnosed essential hypertension.

Objectives: Left ventricular (LV) synchronous contraction is impaired in patients with hypertension (HT). The deleterious effects of HT on cardiovascular system are more evident in patients with nondipper HT than dippers. In this study, we aimed to investigate the effect of nondipping HT on LV systolic synchronicity compared with dippers and controls.

Increased epicardial fat thickness is associated with low grade systemic inflammation in metabolic syndrome.

Objectives: Epicardial fat tissue is a type of visceral adipose tissue that functions as a metabolically active endocrine organ. Most components of metabolic syndrome (MetS), especially visceral obesity, are associated with a low-grade systemic inflammatory state. In this study, we aimed to assess the relationship between echocardiographic epicardial fat thickness (EFT), MetS, the components of MetS, and high sensitivity C-reactive protein (hs-CRP) levels in patients with MetS.

Impaired coronary flow reserve evaluated by echocardiography is associated with increased aortic stiffness in patients with metabolic syndrome: an observational study.

Objective: Metabolic syndrome (MetS) is a strong predictor of cardiovascular events and coronary flow reserve (CFR), an indicator of microvascular function, has been found to be impaired in MetS. Aortic stiffness (AS) is a simple and effective method for assessing arterial elasticity. The aim of this study was to evaluate whether there is an independent association of impaired coronary flow and aortic elasticity in patients with MetS.

[Primary percutaneous coronary intervention for acute myocardial infarction in elderly aged 75 years and over: in-hospital mortality and clinical outcome].

Objectives: We aimed to determine the in-hospital mortality and clinical outcome of patients older than 75 years who were admitted to our high-volume tertiary center with ST-elevation myocardial infarction (STEMI) and treated with primary percutaneous intervention (PCI).

Study Design: Our study included patients over 75 years old who were admitted with STEMI and underwent primary PCI at our center between January 2008 and September 2011. We retrospectively collected data from our hospital records for 1165 patients with STEMI.

Impaired coronary flow reserve is associated with increased echocardiographic epicardial fat thickness in metabolic syndrome patients.

Objectives: Metabolic syndrome (MetS) is a strong predictor of cardiovascular events and coronary flow reserve (CFR), an indicator of microvascular function, has been found to be impaired in MetS. Epicardial fat thickness (EFT) reflects visceral adiposity and is considered an important cardiometabolic marker. In this study, we aimed to examine the presence of an association between CFR and EFT in MetS patients.
