Carcinogenic and toxic molecules produce DNA adducts that contribute to the development of atherosclerosis. Genetic polymorphisms xenobiotic-detoxified enzymes, which control level adducts, may affect both enzymatic activity individual susceptibility coronary artery disease (CAD). In this study we investigated effects genetic CYP1A1*2C, GSTT1, GSTM1 enzymes on CAD risk in a Turkish population. Genotypes were determined for 132 patients 151 healthy controls by polymerase chain...

Sodium-glucose co-transporter-2 inhibitors (SGLT-2i) are a new class of drugs that lower blood glucose and reduce mortality in heart failure patients with reduced ejection fraction (HFrEF). They also have antioxidant effects. The exact mechanism SGLT-2i is unknown. This study investigated the effects on asprosin, matrix metalloproteinase (MMP), tissue inhibitor MMP (TIMP-1) concentrations echocardiographic measurements strain left chamber.

Lower extremity arterial disease (LEAD) is a well-established risk factor for concomitant coronary artery (CAD). There are no published data combining all three lower limb segments (aortoiliac, femoropopliteal and below the knee vessels) in order to estimate CAD severity LEAD patients. Herein has been derived new scoring system this purpose, which uses wellknown TASC II classification, Syntax score and, first time medical literature, score.The study population consisted of 178 patients who...

Background and Aims Few studies have shown the direct effect of familial hypercholesterolemia ( FH ) on myocardial systolic function. Studies focused heterozygote patients but not homozygote ones, they did perform genetic analyses. We aimed to evaluate all types with using potentially more sensitive speckle tracking echocardiography STE technique identify early left ventricular LV dysfunction. Methods Genetic analyses were conducted for LDL ‐receptor, PCSK 9, ApoB100. Nine homozygote, two...

Background Cerebral infarction in patients with atrial fibrillation (AF) may clinically vary from being silent to catastrophic. Silent cerebral (SCI) is the neuronal injury absence of appearent stroke or transient ischaemic attack. Serum neuron specific enolase (NSE) suggested be a valid surrogate biomarker that allows detect recent injury. We aimed evaluate incidence SCI by positive NSE levels non-valvular AF (NVAF) on oral anticoagulants.Methods Blood samples for were collected 197...
