Increased prevalence of cardiac arrhythmias and transient episodes of myocardial ischemia in hypertensives with left ventricular hypertrophy but with…
1997
To evaluate the behavior of cardiac arrhythmias (CA) and transient episodes of myocardial ischemia (TEMI), in relation to the circadian pattern of blood pressure in patients suffering from arterial hypertension, with or without echocardiographically ascertained left ventricular hypertrophy (LVH), we studied 128 patients, 87 men (M) and 41 women (F), aging from 21 to 76 years, subdivided into two groups: Group I, including 66 patients with LVH (45 M and 21 F; mean age of 53.7 ± 9.1 years; Group II, including 62 patients without LVH ( 42 M and 20 F; mean age of 49.7 ± 9.5 years). Office blood pressure (OBP) as well as nighttime ambulatory blood pressure (ABP) were higher in patients with LVH …
Measurement of the local aortic stiffness by a non-invasive bioelectrical impedance technique.
2011
International audience; Aortic stiffness measurement is well recognized as an independent predictor of cardiovascular mortality and morbidity. Recently, a simple method has been proposed for the evaluation of the local aortic stiffness (AoStiff) using a non-invasive bioelectrical impedance (BI) technique. This approach relies on a novel interpretation of the arterial stiffness where AoStiff is computed from the measurement of two new BI variables: (1) the local aortic flow resistance (AoRes) exerted by the drag forces onto the flow; (2) the local aortic wall distensibility (AoDist). Herein, we propose to detail and compare these three indices with the reference pulse wave velocity (PWV) mea…
An Eighteen-Minute Submaximal Exercise Test to Assess Cardiac Fitness in Response to Aerobic Training
2018
Romagnoli, M, Alis, R, Sanchis-Gomar, F, Lippi, G, and Arduini, A. An 18-minute submaximal exercise test to assess cardiac fitness in response to aerobic training. J Strength Cond Res 32(10): 2846-2852, 2018-We aimed to evaluate the utility of a submaximal heart rate recovery (HRR) test to monitor changes in cardiac fitness after aerobic training. Twenty healthy subjects were assigned to a control (n = 10) or a training (n = 10) group. Subjects in the training group performed 8 weeks of bicycle training, followed by 8 weeks of detraining. Heart rate recovery was assessed after exercises at 65% and 80% HRmax. The HRR test was performed at weeks 0 (W0), 4 (W4), 8 (W8), and 16 (W16) in the tra…
Clinical characteristics and determinants of the phenotype in TMEM43 arrhythmogenic right ventricular cardiomyopathy type 5.
2020
Arrhythmogenic right ventricular cardiomyopathy type V (ARVC-5) is the most aggressive heterozygous form of ARVC. It is predominantly caused by a fully penetrant mutation (p.S358L) in the nondesmosomal gene TMEM43-endemic to Newfoundland, Canada. To date, all familial cases reported worldwide share a common ancestral haplotype. It is unknown whether the p.S358L mutation by itself causes ARVC-5 or whether the disease is influenced by genetic or environmental factors. The purpose of this study was to examine the phenotype, clinical course, and the impact of exercise on patients with p.S358L ARVC-5 without the Newfoundland genetic background. We studied 62 affected individuals and 73 noncarrie…
PQ Interval in Patients With Fabry Disease
2010
Fabry disease (FD) is an X-chromosomal inherited lysosomal storage disease resulting in intracellular storage of globotriaosylceramide. Cardiac involvement is most frequently manifested as left ventricular hypertrophy. However, patients with FD may also have from various conduction abnormalities particularly affecting atrioventricular (AV) conduction. The present study was designed to analyze primarily AV conduction abnormalities on baseline electrocardiograms of patients with FD and to investigate the correlation with echocardiographic findings. Electrocardiograms at rest of 207 patients with FD were compared to echocardiograms. PQ-interval shortening and first-degree AV block could be fou…
Relation of endocrine and cardiac findings in acromegalics
1992
Cardiac involvement in 32 acromegalics was related to endocrine parameters, clinical score and duration of the disease as well as compared to that of 50 controls free of cardiac disease. Stress ECG, 24h Holter monitoring and echocardiography revealed that supraventricular premature complexes did not occur more often in acromegalics than in controls, both prevalence and severity of ventricular arrhythmia, however, were higher in patients compared to controls: 15/32 (48%) acromegalics had complex ventricular arrhythmia as compared with 6/50 (12%) normal subjects (p less than 0.01). Repetitive ventricular arrhythmia was manifest in 10/32 (31%) patients but only in 4/50 (8%) controls (p less th…
Effects of drug therapy on cardiac arrhythmias and ischemia in hypertensives with LVH.
2001
Left ventricular hypertrophy (LVH) in hypertensive subjects is associated with an increased prevalence of ventricular arrhythmias. To evaluate the effect of antihypertensive treatment on cardiac arrhythmias (CA) and transient episodes of myocardial ischemia (TEMI), we studied 46 hypertensive patients with LVH, divided into four groups randomly treated with enalapril, hydrochlorothiazide (HCTZ), atenolol, or verapamil (SR-V) for 6 months. Office blood pressure and office heart rate values were recorded, in basal conditions, after 1 and 6 months of treatment, and all patients underwent echocardiography, electrocardiographic Holter monitoring, and stress testing. All drugs significantly lowere…
Experience in the long term use of new antiarrhythmic drugs.
1985
Meinertz et a1. (1984) investigated the long term efficacy and tolerability of flecainide in patients with ventricular arrhythmias. 15 patients were studied, 8 women and 7 men, aged 19 to 74 (mean 58.7) years, with more than 30 ventricular premature complexes (VPCs) per hour, and ventricular arrhythmias of Lown grade IVA or IVB. 11 had coronary artery disease and 2 had idiopathic dilated cardiomyopathy. Patients were excluded on the basis of sustained ventricular tachycardia (VT) [defined as ~ 3 consecutive beats at a rate of> 100 beats/min]; myocardial infarction within the last 6 months; unstable angina; severe congestive heart failure; or conduction abnormalities. Previously unsuccessful…
Wave similarity mapping shows the spatiotemporal distribution of fibrillatory wave complexity in the human right atrium during paroxysmal and chronic…
2005
Introduction: The complexity of waveforms during atrial fibrillation may reflect critical activation patterns for the arrhythmia perpetuation. In this study, we introduce a novel concept of map, based on the analysis of the wave morphology, which gives a direct evidence in the human right atrium on the spatiotemporal distribution of fibrillatory wave complexity in paroxysmal (PAF) and chronic (CAF) atrial fibrillation. Methods and Results: Electrograms were recorded from a 64-electrode catheter in the right atrium of 15 patients during PAF (n = 8) and CAF (n = 7). Wave similarity maps were constructed by calculating the degree of morphological similarity of activation waves (S) at each atri…
