Although borderline isolated systolic hypertension (ISH), defined as a blood pressure of 140 to 159/ 90 mm Hg, is a proven cardiovascular risk factor, the major clinical trials on treatment of ISH have used a cutoff of 160 mm Hg. Moreover, no data exist on the cardiovascular modifications associated with borderline ISH. Therefore, we compared subjects with borderline ISH to subjects with diasto...

BACKGROUND Systemic hypertension is a common cause of left ventricular diastolic dysfunction. However, its prevalence in Nigerians with untreated systemic hypertension is unknown. OBJECTIVE To determine the prevalence of left ventricular diastolic dysfunction in newly diagnosed Nigerians with systemic hypertension using Doppler transmitral inflow and pulmonary venous flow velocities. METHOD...

BACKGROUND Among individuals without hypertension based on clinic blood pressure (BP), it is unclear who should be screened for masked hypertension, defined as having hypertension based on out-of-clinic BP. We hypothesized that individuals with a higher 10-year predicted atherosclerotic cardiovascular disease (ASCVD) risk, calculated using the pooled cohort risk equations, have a higher prevale...

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 measurements...

BACKGROUND We examined the relationship between hypertension subtype and cardiovascular disease incidence and mortality in Chinese adults. METHODS AND RESULTS We conducted a prospective cohort study in a nationally representative sample of 169 871 Chinese men and women aged >or=40 years. Data on systolic (SBP) and diastolic blood pressure (DBP) and other variables were obtained at a baseline ...

Echocardiograms of 143 patients with isolated systolic hypertension were compared to 808 patients with combined (systolic and diastolic) hypertension. All patients met electrocardiographic criteria for left ventricular hypertrophy and were evaluated off medication. Patients with isolated systolic hypertension were older, shorter, weighed less, and were mostly women, but body mass index (BMI) wa...

The aim of this study was to assess characteristic impedance (Zc) of the proximal aorta in young and middle-aged individuals with isolated systolic hypertension (ISH). Zc is an index of aortic stiffness relative to aortic size. In the Dallas Heart Study, 2001 untreated participants 18 to 64 years of age (mean age: 42.3 years; 44% black race) were divided into the following groups based on offic...
