The influence of atrial systole on the left ventricular function curve (stroke volume vs end-diastolic pressure or end-diastolic diameter) and on the left ventricular end-diastolic pressure diameter relation was studied in nine anesthetized, open-chest dogs whose atrioventricular (AV) node had been completely blocked. Measurements were made during volume loading with the pericardium closed and ...

Despite impressive progress in diagnosis, treatment and control of hypertension, this symptom is still one of the major causes of brain and kidney disease as well as cardiac insufficiencies. Since the control of blood lipids, glucose and body weight are highly important in the prevention and treatment of hypertensive drugs, this epidemiologic study was carried out in Islamshahr, 30 Km. to The S...

The effects of alterations in the diastolic filling pressure of the right ventricle on left ventricular (LV) geometry and filling pressure were studied in six isolated, supported canine hearts. This experimental preparation permitted graded increments in right ventricular (RV) end-diastolic pressure while LV cardiac output, heart rate, and mean aortic pressure were held constant. Endocardial ra...

  Background: Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in children. Children with ADHD usually have low blood pressure and weight disorders. Therefore, the present randomized clinical trial was conducted to evaluate the effect of Dietary Approaches to Stop Hypertension (DASH) on weight and blood pressure of children with ADHD. Methods: In ...

Concepts about the relation between blood pressure and outcomes have evolved over the last 20 years from a sole emphasis on diastolic blood pressure to include both systolic blood pressure and pulse pressure. 3 Recently the Framingham heart study has provided further longitudinal data on the natural evolution of blood pressure over a person’s lifetime. The systolic pressure rises linearly betwe...

introduction: obesity is an independent risk factor in developing cvd, type ii diabetes, and gall bladder disease, different types of cancers, osteoarthritis and mortality. weight gain during adult life, especially during the third and fourth decades, is associated with increased blood pressure. methods: random samples of nearly 1493 men and women aged between 16 to 85 years old were selected f...

The practicality of vigorous lowering of systolic pressure in diabetes to 130 mmHg remains uncertain. Baseline blood pressure data from several recent trials indicate that, in diabetic subjects, there is nearly a fourfold excess in systolic pressure (the difference between baseline pressure and target pressure) over diastolic pressure with respect to the recommended systolic/diastolic target pr...

The effects of synthetic chicken VIP (an octacosapeptide corresponding to the entire sequence of chicken VIP) on pancreatic blood flow and on systemic arterial pressure was examined in dogs. The relationship between pancreatic blood flow and systemic arterial pressure in response to synthetic chicken VIP was also investigated. Pancreatic blood flow increased promptly and significantly with exog...
