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...

Background Right ventricular-pulmonary arterial coupling plays an important role in the occurrence of right ventricular failure. Ventricular-arterial coupling is defined as Ea/ Emax. Ea is the effective arterial elastance and an index of the post-load, and includes vascular resistances, vessel compliance, vascular impedance, systolic and diastolic time intervals. Ea = (arterial end-systolic pre...

The left ventricular end-systolic pressure-volume relationship is a load-insensitive measure of left ventricular performance. The relationship at end-systole between left ventricular pressure and dimension is more easily obtained, but the conflicting results of previous studies make it unclear if it has the same properties as the left ventricular end-systolic pressure-volume relationship. To ad...

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 patient was a 19 year-old woman with the diagnosis of resistant hypertension, although she was under treatment of three classes of anti-hypertensive drugs (beta blocker, angiotensin receptor blocker, diuretic) for more than one year. In physical examination there was only a significant difference between the systolic blood pressure of upper and lower extremities (200 vs. 120 mmHg), without ...

background: hospitalization in the coronary care unit (ccu) is a concern for patients and their companions. different studies have presented conflicting results about the effect of visitors on physiological parameters of patients. the purpose of this study was to determine changes in physiological parameters (systolic and diastolic blood pressure and heart rate) due to presence of visitors at t...

Background & Aims: Endothelin_1 secreted by endothelial cells has been identified as the strongest vascular constrictor. The aim of the present study was to investigate the role of concurrent training on plasma concentration of endothelin_1 and its relationship with blood pressure of old women. Methods: A total of 20 menopause women (Mean age: 67.47±5.92 years, mean body length: 152.92±7.52cm, ...

In a cross section study performed in Rauch in 1997 we found a high prevalence of hypertension and low levels of treatment and control. To evaluate the impact of the community-based intervention activities on blood pressure (BP), we made a cohort study in 1526 inhabitants aged between 15 and 75 years in 2003. The initial study, the advice to consult the family doctor when alterations were found...

background thrombolytic therapy in patients with sub-massive pulmonary embolism (smpte) needs further assessment. objectives the current study aimed to assess a potential benefit of thrombolytic and non-thrombolytic therapy in patients with smpte. patients and methods one hundred-nineteen patients were enrolled with smpte from 2006 to 2010 in the tertiary care center of rajaie medical and resea...
