Metabolic syndrome, organ damage and cardiovascular disease in treated hypertensive patients. The ERIC‐HTA study
2007
The aim of this study is to assess the relationship among metabolic syndrome (MS), target organ damage (TOD) and established cardiovascular disease (CVD) in non-diabetic hypertensive elderly patients. ERIC-HTA is cross-sectional, multicentre study carried out in primary care, on hypertensive patients aged 55 or older. MS was defined by the NCEP-ATP III criteria, using body mass index (28.8 kg/m(2)) instead of abdominal perimeter. In 8331 non-diabetic hypertensive patients (3663 men and 4668 women, mean age 67.7 years), the prevalence of MS was 32.6% (men: 29.0%; women: 36.8%). A linear association was observed between a greater number of components of MS and a greater prevalence of left ven…
Circulating adiponectin: a cardiometabolic marker associated with global cardiovascular risk
2015
OBJECTIVE This study was designed to evaluate the relationship among circulating adiponectin (ADPN), left ventricular mass (LVM) and cardiometabolic comorbidities in subjects at higher global cardiovascular risk (score of “ Cuore Project “) METHODS. 115 consecutive subjects were grouped according to normal or low ADPN levels. Left ventricular internal diameter (LVID/h), total LV mass (LVM), LVM index (LVMI), relative wall thickness (RWT), LV ejection fraction by echocardiography and diastolic parameters, by pulsed-wave Doppler were calculated. RESULTS Low-ADPN subjects were characterized by a significant higher prevalence of some cardiometabolic comorbidities (obesity, visceral obesity, dia…
Hypoadiponectinemia, cardiometabolic comorbidities and left ventricular hypertrophy
2014
This study was designed to evaluate the prevalence of cardiometabolic comorbidities and the changes in left ventricular geometry and function in 135 subjects subgrouped according to low or normal total adiponectin plasma (ADPN) levels. Left ventricular (LV) internal diameter/height, total LV mass (LVM) and LVM index (LVMI), relative wall thickness (RWT), LV ejection fraction by echocardiography and diastolic parameters by pulsed-wave Doppler were calculated. Body mass index (BMI) (p < 0.0001), waist-to-hip ratio (p < 0.03), triglycerides (p < 0,001), prevalence of obesity (p < 0.005), visceral obesity (p < 0.003), left ventricular hypertrophy (LVH) (p < 0.001), metabolic syndrome (p < 0.000…
Obesity related changes in cardiac structure and function: role of blood pressure and metabolic abnormalities.
2019
BACKGROUND: It has been reported that changes in cardiac structure and ventricular function associated with obesity have to be attributable to hemodynamic and non-hemodynamic alterations. Accordingly, the aim of this was to evaluate left ventricular hypertrophy (LVH) prevalence and its effect on left ventricular systolic and diastolic function in a cohort of obese patients. MATERIALS AND METHODS: LV internal diameter (LVID), left ventricular mass (LVM) and LVM/height2.7(LVMI), relative wall thickness (RWT), LV ejection fraction (LVEF), E/A ratio, isovolumic relaxation time, deceleration time of E velocity by echocardiography and pulsed-wave Doppler and total circulating adiponectin (ADPN) b…
Cardiac arrhythmias as correlated with the circadian rhythm of arterial pressure in hypertensive subjects with and without left ventricular hypertrop…
1990
To evaluate the relationship among supraventricular and ventricular arrhythmias with blood pressure and heart rate (HR) values, we studied 2 groups of 20 hypertensive men with (group I) and without (group II) left ventricular hypertrophy. Ambulatory electrocardiographic tracings were recorded continuously, together with ambulatory arterial pressure. Systolic (SBP) and diastolic (DBP) blood pressure values measured over 24 h showed no difference between the two groups, but we found greater variability in SBP in group I. The incidence of ventricular and supraventricular arrhythmias was significantly higher in patients of group I; moreover, we found a strong correlation between the incidence o…
Inappropriately high left ventricular mass: Marker of very high cardiovascular risk in patients with chronic kidney disease
2012
There is increasing knowledge of the burden of cardiovascular (CV) diseases affecting patients with chronic kidney disease (CKD). CV diseases are the main cause of death in the CKD population, and the majority of patients with CKD die before ever reaching the end-stage renal disease; in fact, for patients with CKD, the risk of a fatal CV event is much higher than the risk to develop end-stage renal disease. Although patients with CKD manifest a high prevalence of traditional CV risk factors, this does not fully account for the burden of CV diseases in CKD.
Physical training and connective tissues in young mice-heart
1976
The effect of physical training on the chemical properties of the heart tissues was studied in male mice of NMRI-strain. The mice to be trained and their controls were about 2 weeks old at the beginning of the training, which took place on 5 degrees inclined treadmill 5 days a week for 3-22 weeks. The duration of daily exercise was progressively increased over the first 3 weeks. The final daily exercise bouts were 50 and 80 min for moderate programs and 180 min for the intensive program at a speed of 30 cm/s. The whole heart or the ventricles were used for the analyses. We found no significant changes related to training in the concentrations of nitrogen, hexosamines, and hydroxyproline bot…
Long-Term Follow-Up of Children with Surgically Treated Vesicorenal Reflux: Renal Growth
1991
Renal growth after successful surgical correction of vesicoureterorenal reflux (VUR) in childhood was observed in 137 female and 22 male patients over a mean follow-up period of 10.5 years. The renal parenchymal area was determined using a compensatory planimeter. For each measured value, the standard deviation score (SDS) was calculated by comparison with a normal population. On average, renal growth after reflux operation nearly paralleled the expected normal growth rate. Scarred kidneys had a worse growth prognosis than refluxing renal units (RU) without renal damage, growth retardation being correlated with the degree of pyelonephritic changes. The diminished growth rate of scarred kidn…
Selected enzyme activities in mouse cardiac muscle during training and terminated training
1984
We studied the effects of running-training, heavy exercise and termination of training on the heart weight, the ratio heart to body weight and the cardiac muscle activities of actomyosin ATPase, citrate synthase, succinate dehydrogenase, cytochrome c oxidase, malate dehydrogenase, adenylate kinase and beta-glucuronidase with adult male NMRI-mice. Stable hypertrophy (6-7%), estimated by the ratio heart or ventricle weight to body weight, was achieved by 28 exercises and it was dependent on the running speed (20 vs. 25 m X min-1). The withdrawal of training for 5-61 days did not permanently decrease the heart weight or the heart to body weight ratio to the level of sedentary controls. The act…
