The effects of developing perinephritic hypertension (2-3 weeks) and a more stable period of perinephritic hypertension (approximately 14 weeks) were examined on indexes of left ventricular (LV) diastolic function in conscious, chronically instrumented dogs. The complete period of diastole was studied using indexes of isovolumic relaxation (tau), early filling (LV +dD/dt), and stiffness (myocar...
BACKGROUND Studies consisting mostly of whites have shown that the prevalence of masked hypertension differs by prehypertension status. Using data from the Jackson Heart Study, an exclusively African American population-based cohort, we evaluated the association of masked hypertension and prehypertension with left ventricular mass index and common carotid intima media thickness. METHODS AND R...
OBJECTIVE To delineate more precisely an operational threshold for making clinical decisions based on ambulatory blood pressure (ABP) measurement by studying the ABP in subjects who were diagnosed as either normotensive or hypertensive by conventional blood pressure (CBP) measurement. SUBJECTS Twenty-four research groups recruited 7069 subjects. Of these, 4577 were normotensive (systolic CBP ...
AIM To determine if Color Doppler myocardial imaging could provide evidence of diastolic dysfunction in patients with hypertension whose pulse-wave Doppler parameters were normal. METHOD The study included 33 patients (mean age 48+/-7.3 years) and a control group of 13 sex- and age-matched healthy individuals. Patients were divided into two groups according to mean blood pressure (BP) values ...
Left ventricular (LV) diastolic dysfunction, particularly relaxation abnormalities, are known to be associated with the development of LV hypertrophy (LVH). Preliminary human and animal studies suggested that early LV diastolic dysfunction may be revealed independently of LVH. However, whether LV diastolic dysfunction is compromised before the onset of hypertension and LVH remains unknown. We t...
INTRODUCTION This study aimed to determine hypertension prevalence and levels of awareness, treatment and control of hypertension among diabetic patients using data from the VANK study. METHODS The sample consisted of 221 men and women (122/99) diagnosed with type 2 diabetes. Semi-structured interviews were conducted with all participants. Controlled hypertension definition was based on havin...
We performed exome-wide association studies to identify genetic variants that influence systolic or diastolic blood pressure or confer susceptibility to hypertension in Japanese. The exome-wide association studies were performed with the use of Illumina HumanExome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays and with 14,678 subjects, including 8215 individuals with hypertension...
introduction pulmonary hypertension is common among patients with hyperthyroidism, and graves’ disease constitutes the most common cause of thyrotoxicosis. case presentation we report the case of a female patient admitted to the cardiology department with shortness of breath and pretibial myxedema. the diagnostic work-up revealed combined pre- and post-capillary pulmonary hypertension due to gr...
The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
