Article Synopsis
  • The study examined the relationship between inflammation, oxidative stress, and heart function in 100 NSTEMI patients with varying kidney health.
  • It found that lower ejection fraction (EF) was linked to higher levels of inflammatory markers like BNP and hs-CRP and lower kidney function as indicated by glomerular filtration rate (GFR).
  • A predictive model was developed to identify patients with severe cardiac injury, based on markers of inflammation and oxidative stress.

Context • Pleasant music that evokes a positive emotional response may activate brain pathways of the insular cortex, central nucleus of the amygdala, and lateral hypothalamus, which are involved in the integration of emotional and ambient sensory input, with corresponding autonomic responses. Exercise training can improve endothelium-dependent vasodilatation, both in epicardial coronary vessels and in resistance vessels, for patients with coronary heart disease. Objective • The aim of the present study was to evaluate the effects on endothelial function when patients with stable coronary artery disease (CAD) listened to their favorite music.

Background: A bout of intense physical activity has been shown to transiently impair endothelial function; however, the underlying mechanisms are unclear.

Aim: The purpose of the review was to assess the impact of a bout of physical exercise induced by exercise stress echocardiography, on blood concentration of the endogenous inhibitors of nitric oxide synthase, asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA), in patients with atherosclerosis.

Methods: Overall, 83 study participants were enrolled, 25 coronary artery disease (CAD) patients, 20 age and sex-matched asymptomatic study participants with at least one risk factor for CAD, and 38 healthy controls.

Introduction: Cardiovascular (CV) diseases and bone fractures due to osteoporosis are the leading causes of death in the elderly.

Objective: The aim of this study was to demonstrate a correlation between the overall risk for CV events, and low bone density in postmenopausal women, and its impact on the incidence of serious CV events.

Methods: Our prospective study involved 300 postmenopausal women.

Background: The EUROASPIRE surveys showed high rates of modifiable cardiovascular risk factors in patients with coronary heart disease, identified after coronary artery bypass graft, percutaneous coronary intervention or myocardial infarction, with time trends in preventive cardiology over more than a decade.

Aim: The aim of this study was to test the implementation of European recommendations for cardiac rehabilitation and secondary risk prevention programmes in the population of coronary heart disease patients from Serbia.

Subjects And Methods: A total of 665 consecutive coronary heart disease patients (432 men, 233 women, aged 59.

Background: The aim of the present study was to assess the impact of reversible myocardial ischemia, provoked by acute physical activity during an exercise stress echocardiography (ESE), on nitric oxide (NOx) and asymmetric dimethylarginine (ADMA) production in patients with high risk for coronary heart disease (CHD).

Material/methods: An overall of 45 patients (27 men, 18 women; mean age, 55.87+/-6.

Regular physical activity is meant to be one of the most important nonpharmacological tools in reducing overall cardiometabolic risk since it significantly regulates body weight, blood pressure, blood glucose and lipid levels, and it also improves strength flexibility and quality of life and reduces stress. However, it should be individually prescribed, according to the patient's previous health status, individual desires and goals. Previous examinations (exercise stress testing, searching for vascular and neurological complications) are highly recommended in order to avoid potential risks (cardiovascular, microvascular, macrovascular, musculosceletal) ones.

Aim: The aim of the present study was to assess the impact of the interval exercise training (IET) vs. steady state exercise training (SSET) on nitric oxide production, through changes of circulating blood markers of endothelial function, including stable end-products of nitric oxide (NOx) and S-nitrosothiols (RSNOs) in patients with left ventricular dysfunction (LVD).

Patients And Methods: The impact of the IET vs.

Aim: The aim of the present study was to investigate the value of the urine cell glycoprotein 1 (PC-1), aminopeptidase N (APN), N-acetyl-beta-D-glucosaminidase (NAGA), and dipeptidylpeptidase IV (DPP IV) in the evaluation of tubular damage in patients with primary glomerulonephritis, diabetic nephropathy, and lupus nephritis.

Subjects And Methods: PC-1, APN, NAGA, and DPP IV activities were determined in serum, urine, and lymphocytes of 178 subjects, including 10 patients with membranous nephropathy, 38 with IgA nephropathy, 29 with lupus nephritis, 51 with diabetic nephropathy, and 50 control subjects.

Results: Urinary PC-1 excretion in IgA nephropathy group was significantly higher (p < 0.

Aim: The aim of the present study was to investigate not only the effects of aerobic exercise on overall cardiovascular risk factors profile and oxidative stress in obese, type 2 diabetic patients, but to elucidate if those effects depended on the previously estimated Systematic Coronary Risk Evaluation (SCORE) risk.

Subjects And Methods: Changes in several well-established cardiovascular risk factors and oxidative stress-defense parameters were measured in a total of 30 previously sedentary, obese type 2 diabetic patients, including 16 low-risk (SCORE < 5%, aged 48.8 +/- 6.

Aim: The aim of the present study was to investigate the prevalence of the PC-1 121Q allele and to test its association to cardiovascular risk factors in type 2 diabetes mellitus (DM) patients.

Methods: A total of 103 unrelated Caucasians from Serbia, including 71 DM patients without CHD (aged 59.4 +/- 8.

Objective: Reactive oxygen species play a crucial role in the pathogenesis of diabetic nephropathy (DN). The present study was performed to assess oxidative stress parameters-thiobarbituric acid reactive substances (TBARS), reactive carbonyl derivates (RCDs), and total sulfhydryl groups (TSHGs)-in serum and urine of patients with DN.

Methods: All parameters were determined in patients with type 2 and type 1 diabetes mellitus and microalbuminuria (DMT2-MIA, DMT1-MIA, respectively) and patients with type 2 diabetes mellitus and macroalbuminuria (DMT2-MAA) compared to healthy controls.

Increased urinary albumin excretion is a strong predictor for the development of overt diabetic nephropathy and overall cardiovascular morbidity and mortality in patients with type 2 diabetes. In a previous study, regular aerobic physical activity in overweight/obese patients with type 2 diabetes mellitus was found to have significant beneficial effects on glycemic control, insulin resistance, cardiovascular risk factors, and oxidative stress. The aim of the present study was to investigate the effects of aerobic exercise in the same cohort of type 2 diabetic patients on urinary albumin excretion, serum levels and urinary excretion of enzymes, tubular damage, and metabolic control markers in type 2 diabetic patients.

Background: Metabolic syndrome (MS) is a clinical feature, closely associated with insulin resistance, one of the prime underlying causes of overall cardiovascular morbidity, including coronary heart disease (CHD). Considering the association between PC-1 121Q genotype and insulin resistance phenotype, the aim of the present study was to investigate the contribution of PC-1 K121Q polymorphism to the development of MS and its concomitant disorders in CHD patients.

Methods: A total of 130 Caucasians from Serbia, including 80 CHD patients (aged 59.

Streptococcus pyogenes is the most prevalent cause of tonsillopharyngitis in children. The drug of choice for infections caused by this microorganism is penicillin. The problem of treating such infections arises when erythromycin-resistant strains occur.
