Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients different phenotypes of near normal, and supernormal left ventricular (LV) function. To assess the value resting LV elastance (also known as force) transthoracic echocardiography (TTE) to identify HFpEF phenotypes. In prospective, observational, multicenter study, 2380 were recruited from July 2016 May 2024. Systolic blood pressure (SBP) was measured. We assessed end-diastolic volume (EDV),...
Delay is the enemy for patients with acute myocardial infarction. It would be helpful hospital cardiologist to interpret patient's electrocardiogram(ECG) before arrival of ambulance. The aim our study was determine whether ECG transmission from an ambulance feasible and assess time savings. An equipped recorder, which connected a notebook computer coupled acellular telephone hospital-based station. Paramedics needed 2 min (SD 0.5) record on move 34 s(SD 14) transmit it. arrived 15.5 6.5)...
<h3>Background</h3> Exercise improves the clinical outcome of patients with coronary artery disease (CAD); however, ideal exercise duration for each patient remains unclear. <h3>Objective</h3> To investigate effects on arterial elastic properties and antioxidant/pro-oxidant mechanisms in CAD. <h3>Design, setting, patients, interventions</h3> Sixty male CAD were randomised into two groups, underwent 30 min or 60 a crossover design 2 weeks9 wash-out period. In all participants aortic radial...
Haemodynamic parameters during and after exercise test seem to have a role in predicting cardiovascular events. We sought evaluate the potential different responses capacity, heart rate blood pressure levels relation major disease risk factors, among individuals undergoing tolerance testing. Consecutive (N = 12,327), aged 55 ± 11.8 years, underwent testing, using Bruce protocol. Obese participants showed higher values of peak systolic diastolic (p < 0.01), with no differences. Diabetic...
Goal: We introduce a novel approach to estimate cardiac output (CO) and central systolic blood pressure (cSBP) from noninvasive measurements of peripheral cuff-pressure carotid-to-femoral pulse wave velocity (cf-PWV). Methods: The adjustment previously validated one-dimensional arterial tree model is achieved via an optimization process. In the loop, compliance resistance generic as well aortic flow are adjusted so that simulated brachial diastolic pressures cf-PWV converge towards measured...
Cardiovascular diseases (CVD) is associated with deteriorating of quality life (QOL) and exercise capacity (EC) but less known on how EC interplays QOL. The present study explores the relationship between cardiovascular risk factors in people who cardiology clinics. A total 153 adult presentations completed SF-36 Health Survey provided data for hypertension, diabetes mellitus, smoking, obesity, hyperlipidemia history coronary heart disease. Physical was assessed by treadmill test. were...
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 distinguish the results in patients with MVP. Methods We studied 218 consecutive ( years, 103 males) MVP (according echocardiographic study), and treadmill ET performed due multiple cardiovascular risk factors or angina-like symptoms. A coronary angiography detect artery disease (CAD). Results From patients, 90...
Cardiovascular disease and complications are often mediated by the development rupture of atherosclerotic plaques. Plaque composition is a major factor that determines plaque vulnerability. Intravascular ultrasound (IVUS) spectral analysis radio frequency signal provide an in vivo tissue characterisation plaques, known as virtual histology (VH–IVUS). In VH–IVUS analysis, four histological components classified: fibrous, fibro/fatty, necrotic core calcium. Existing technology only area each...
Blood pressure (BP) nondipping has been associated with target-organ damage (TOD) and adverse outcomes in hypertension. Diverse definitions of status appear the literature, regarding BP components taken into account. Aim this study was to compare effects isolated systolic, diastolic combined systolic on various indices TOD.From 630 consecutive subjects never-treated essential hypertension stage I-II, we selected 279 who were consistently nondippers (SND, n=76) (DND, n=64) (SDND, n=139) two...
We present assessment of chest pain patients by multiparametric dobutamine stress echocardiography to differentiate inducible ischemia with obstructive coronary artery disease and no disease. In addition the classical regional wall motion abnormality, we illustrate how flow velocity reserve Doppler assists diagnosing microvascular dysfunction. (Level Difficulty: Advanced.).
Objective The accuracy of treadmill exercise testing to detect coronary artery disease is limited in women. This study was undertaken evaluate whether QRS score can improve the Methods population consisted 114 women with angina-like symptoms, who underwent both and angiography. impact on standard ST-segment based diagnostic ability studied. Results Incorporation criteria significantly enhanced sensitivity (from 59 80%), specificity 40 94%) 50 87%) testing. shown reduce false-positive results...
There is one mathematical element with strong historical and philosophical background that exhibits remarkable properties applications; the golden ratio (phi). Mathematically, equals approximately 1.61803. A rather provocative geometrical analysis of arterial pulse according to was recently described, herein, we aim set out hypothesis individuals blood pressure (BP) values follow may have different prognosis than those whose BPs deviate from divine proportions.We used published data National...
Total exercise duration and abnormal QRS score values are treadmill testing (TET) prognostic parameters that have been shown to be significantly independently associated with cardiac mortality. We evaluated the value of a new index (M score, Michaelides score) incorporating TET in simple index.In this study, we included 626 patients, who underwent coronary arteriography. Cardiac catheterization showed presence artery disease 64.3% these patients. The M was calculated by adding Athens (in...
Aims The aim of this study is to investigate whether atropine when administered in persons without glaucoma during dobutamine stress echocardiography causes pupillary dilation. Methods and Results 144 patients referred for (DSE) any history were observed. 39 excluded from the because they did not receive atropine. Pupil diameter was measured at same light conditions before after each session. 105 received DSE doses 0.1 mg 1.25mg (most 0.25-0.75mg). For total 210 examined eyes pupil remained...
