Acute exercise-induced inflammatory and thrombotic response in hypertensive patients.

Purpose: Vigorous physical activity may acutely trigger the onset of an acute coronary syndrome especially in sedentary persons with established cardiovascular risk factors such as arterial hypertension. The rupture of an inflamed coronary plaque and the activation of the coagulation cascade are the main underlying mechanisms. The present study aimed to determine the effect of acute exercise on the inflammatory and thrombotic response in patients with arterial hypertension as compared to normotensive peers.

Pleiotropic beneficial cardiometabolic actions of a high-purity eicosapentaenoic acid product in high cardiovascular risk individuals.

The ideal approach to the secondary dyslipidemia goal of lowering triglycerides (TG) is not well established. The available ω-3 fatty acid products differ from each other in composition and content. The purpose of the present study was to investigate the effect of a highly purified eicosapentaenoic acid (EPA) formulation on cardiometabolic biomarkers in high cardiovascular (CV) risk patients.

Blood Pressure-Lowering Effect of Newer Antihyperglycemic Agents (SGLT-2 Inhibitors, GLP-1 Receptor Agonists, and DPP-4 Inhibitors).

The prevalence of arterial hypertension is high in patients with diabetes mellitus (DM). When DM and hypertension coexist, they constitute a dual cardiovascular threat and should be adequately controlled. Novel antihyperglycemic agents, including sodium-glucose co-transporter 2 (SGLT-2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1 RAs), and dipeptidyl peptidase-4 (DPP-4) inhibitors, have recently been used in the treatment of DM.

Radial artery as a graft for coronary artery bypass surgery in the era of transradial catheterization.

Radial artery use as a bypass conduit is well established during the past decades, in terms of both patency and safety. On the other hand, transradial catheterization causes a series of structural and functional changes to the vessel itself. Impairment of nitric oxide-dependent vasodilation and notable decrease in radial artery diameter due to intima thickening and hyperplasia, especially during the first 3 months after its cannulation, constitute some of the most important alterations on the radial artery wall and its function after a transradial coronary catheterization procedure.

Adherence to Treatment, Safety, Tolerance, and Effectiveness of Perindopril/Amlodipine Fixed-Dose Combination in Greek Patients with Hypertension and Stable Coronary Artery Disease: A Pan-Hellenic Prospective Observational Study of Daily Clinical Practice.

Background: Initiation of antihypertensive therapy with a two-drug fixed-dose combination (FDC) in a single tablet may be recommended in patients at high risk of cardiovascular events to improve adherence and effectiveness. Preferred combinations include an angiotensin-converting enzyme inhibitor with a dihydropyridine calcium antagonist.

Objective: This study assessed adherence to and the safety, tolerance, and effectiveness of the perindopril/amlodipine FDC in Greek patients with hypertension and stable coronary artery disease (CAD) over a 4-month period.

Arterial hypertension and aortic valve stenosis: Shedding light on a common "liaison".

Arterial hypertension and aortic valve stenosis are common disorders and frequently present as concomitant diseases, especially in elderly patients. The impact of hypertension on heart haemodynamics is substantial, thus affecting the clinical presentation of any coexisting valvulopathy, especially of aortic stenosis. However, the interaction between these 2 entities is not thoroughly discussed in the European or/and American guidelines on the management of hypertension or/and valvular heart disease.

Neutrophil Gelatinase-Associated Lipocalin as an Early Marker of Contrast-Induced Nephropathy After Elective Invasive Cardiac Procedures.

Background: Contrast-induced nephropathy (CIN) is an acute kidney injury (AKI) defined as serum creatinine (sCr) increase 48 to 72 hours after contrast administration. Because most subjects undergoing invasive cardiac procedures are discharged within 24 hours, sCr is unsuitable for CIN detection.

Hypothesis: In the present study we tested the hypothesis that neutrophil gelatinase-associated lipocalin (NGAL) is superior compared with sCr and other established nephropathy markers in early CIN diagnosis after elective invasive cardiac procedures.

Twenty-Four-Hour Urine α -Microglobulin as a Marker of Hypertension-Induced Renal Impairment and Its Response on Different Blood Pressure-Lowering Drugs.

The purpose of this study was to assess the role of urine α -microglobulin as a marker of hypertension-induced renal damage compared with estimated glomerular filtration rate, (eGFR), urine albumin, and urine albumin-to-creatinine ratio (ACR). Its response on different blood pressure (BP)-lowering drugs was also studied. Sixty never-treated hypertensive patients (65.

The Tree of Sirtuins and the Garden of Cardiovascular Youth.

Sirtuins (SIRTs) are a class of nicotine adenine dinucleotide (NAD+)-dependent proteins which participate in numerous molecular pathways involved in various age-related human diseases, such as type II diabetes, cardiovascular (CV) diseases and cancer. They have a major role in apoptosis, inflammation, oxidative stress and metabolism regulation, traits that have a great impact on CV physiology and pathology. Their unique profile of NAD+ energy dependency makes them an appealing target for human intervention in cellular and metabolic processes.

Apelin and Visfatin Plasma Levels in Healthy Individuals With High Normal Blood Pressure.

Background: High normal blood pressure (BP; 130-139/85-89 mm Hg) is related with increased cardiovascular (CV) risk compared to normal BP (120-129/80-84 mm Hg) or/and optimal BP (<120/80 mm Hg). Low apelin plasma levels have been associated with arterial hypertension and atherosclerosis, while high visfatin plasma levels may promote vascular inflammation and atherosclerotic plaque destabilization and have been evaluated as a marker for identifying stages of essential hypertension. We sought to compare the apelin and visfatin plasma levels between subjects with high normal BP and subjects with normal or optimal BP matched for age, gender, smoking, and body mass index (BMI).

Correlation of 24-Hour Blood Pressure and Heart Rate Variability to Renal Function Parameters in Hypertensive Patients. The Effect of Smoking.

Intrarenal hemodynamics depend on blood pressure (BP), heart rate (HR), and smoking. Although BP levels have been associated with kidney function, the effect of HR levels, BP, and HR variability on renal function are less well clarified. This cross-sectional study sought to determine the association of 24-hour BP and HR variability with kidney function in hypertensive patients, stratified by smoking.

Genetic Variant in the CYP19A1 Gene Associated with Coronary Artery Disease.

The CYP19A1 gene encodes the enzyme aromatase, which is responsible for the biosynthesis of estrogens. The rs10046 polymorphism of CYP19A1 gene has been investigated in two studies on the occurrence of hypertension, but there are no studies on its correlation with coronary artery disease (CAD). We investigated 189 subjects who were hospitalized at "KAT" General Hospital of Athens and underwent coronary angiography.

Antiplatelet and invasive treatment in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency and acute coronary syndrome. The safety of aspirin.

What Is Known And Objective: Aspirin is an important drug in acute coronary syndromes (ACS) and percutaneous coronary interventions (PCI). However, its use is contraindicated in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency (risk for haemolytic anaemia). We report the management of 2 patients with class II G6PD deficiency and non-ST-segment elevation ACS (NSTE-ACS).

2013 ESH/ESC guidelines for the management of arterial hypertension: what has changed in daily clinical practice?

This is a review article aiming to make focus on the changes made in the European Society of Hypertension (ESH)/European Society of Cardiology (ESC) guidelines for the management of arterial hypertension with some criticism for each element discussed in the text. Given that in the real world clinical practice physicians would hardly spend the time needed for studying the 77 pages manuscript of the recently released 2013 ESH/ESC hypertension guidelines, the present review summarizes all the significant updates (along with their clinical implications) compared to the 2007 ESH/ESC hypertension guidelines and the 2009 reappraisal document.

Impaired glucose homeostasis in non-diabetic Greek hypertensives with diabetes family history. Effect of the obesity status.

Arterial hypertension (AH) and diabetes mellitus (DM) are established cardiovascular risk factors. Impaired glucose homeostasis (IGH; impaired fasting glucose or/and impaired glucose tolerance) or pre-diabetes, obesity, and DM family history identify individuals at risk for type 2 DM in whom preventive interventions are necessary. The aim of this study was to determine the glycemic profile in non-diabetic Greek adult hypertensive men and women according to DM family history and the obesity status.

The interplay of exercise heart rate and blood pressure as a predictor of coronary artery disease and arterial hypertension.

Delayed blood pressure (BP) and heart rate (HR) decline at recovery post-exercise are independent predictors of incident coronary artery disease (CAD). Delayed BP recovery and exaggerated BP response to exercise are independent predictors of future arterial hypertension (AH). This study sought to examine whether the combination of two exercise parameters provides additional prognostic value than each variable alone.

Correlation of arm position and exercise test interpretation.

ST-segment changes during exercise testing can be attributed mainly to ischemia, but also, in some patients, to other physiological parameters, such as body position or hyperventilation, making ECG exercise test interpretation more complex. Here we describe the case of a patient who had an electrocardiographically positive exercise test, in order to illustrate the correlation between arm position and ST changes during exercise testing.

The effects of angiotensin receptor blockers vs. calcium channel blockers on the acute exercise-induced inflammatory and thrombotic response.

Arterial hypertension is an established risk factor for acute coronary syndromes, and physical exertion may trigger the onset of such an event. The mechanisms involved include the rupture of a small, inflamed, coronary plaque and the activation of thrombogenic factors. Blood pressure (BP)-lowering treatment has been associated with beneficial effects on subclinical inflammation and thrombosis at rest and during exercise.

The antihypertensive treatment effect on left ventricular diastolic function is reflected in exercise electrocardiogram.

Background/purpose: Exercise electrocardiographic hump sign is associated with uncontrolled arterial hypertension (AH), left ventricular (LV) diastolic dysfunction, and false-positive exercise testing (ET). The aim of this prospective study was to evaluate the antihypertensive treatment effect on hump and on pseudoischemic ST-segment depression and potential correlations to LV diastolic function and mass changes.

Methods: The study comprised 59 non-coronary artery disease patients (45.

Cardiovascular risk factor(s) prevalence in Greek hypertensives. Effect of gender and age.

The aim of this study was to determine cardiovascular (CV) risk factors (RFs) and target organ damage clustering in 21280 Greek hypertensives stratified by gender and age. Glycemic and lipid profile were determined, left ventricular mass index, estimated gromerular filtration rate (eGFR), 10-years CV risk according to Framingham risk score (FRS) and HeartScore (HS) were calculated. Only 10.

Exercise duration as a determinant of vascular function and antioxidant balance in patients with coronary artery disease.

Background: Exercise improves the clinical outcome of patients with coronary artery disease (CAD); however, the ideal exercise duration for each patient remains unclear.

Objective: To investigate the effects of exercise duration on arterial elastic properties and antioxidant/pro-oxidant mechanisms in patients with CAD.

Design, Setting, Patients, Interventions: Sixty male patients with CAD were randomised into two groups, and underwent exercise for 30 min or 60 min in a crossover design with 2 weeks' wash-out period.

Novel methodology for the detection of exercise-induced myocardial wall motion abnormalities by surface electrocardiogram during exercise test.

Background: We investigated whether ischemia-induced wall motion abnormalities during exercise test modify electrical vector variation.

Methods: We performed treadmill exercise test and thallium 201 scintigraphy in 150 normotensives. Beat-to-beat change of direction of S wave in V(1) (reference lead) was compared with that of R wave in V(5) and aVF, representative of anterior and inferior walls, respectively.

ST-Segment Depression in Hyperventilation Indicates a False Positive Exercise Test in Patients with Mitral Valve Prolapse.

Objectives. Mitral valve prolapse (MVP) is a known cause for false positive exercise test (ET). The purpose of this study was to establish additional electrocardiographic criteria to distinguish the false positive exercise results in patients with MVP.

Right-sided chest leads in exercise testing for detection of coronary restenosis.

Background: The incorporation of right-sided chest leads (V(3)R through V(5)R) into standard exercise testing has been reported to improve its diagnostic utility.

Hypothesis: The purpose of this study was to evaluate any improvement in the ability of exercise testing in detecting restenosis, using additional V(3)R through V(5)R leads, in asymptomatic patients undergoing percutaneous coronary intervention (PCI) in the right coronary artery (RCA) or/and left circumflex (LCX).

Methods: We studied 172 consecutive patients (54 +/- 7 years old, 106 males) undergoing PCI in RCA or/and LCX.
