501 Abstract: Diastolic dysfunction is characterized by increased resistance to ventricular filling, inappropriate upward shift of the diastolic pressure-volume relationship and exercise intolerance. Inappropriate tachycardia, decreased diastolic compliance and impaired systolic relaxation lead to diastolic dysfunction. Optimal therapy will depend on the type and pathophysiologic phase of disea...

The Literature review indicates that the high blood pressure has a different prevalence in various population of Iran and in the age group of 35 and above the rate varies from 7% in Qushguai tribe to 30% in Teheran and Anzali. The purpose of this study is to know whether the essential hypertension begins at the early age of life; and also to standardizing the normal value of blood pressure in c...

BACKGROUND Overloading the left ventricle in systole (pressure overload) is associated with a distinct morphological response compared with overload in diastole (volume overload). METHODS AND RESULTS We designed a novel computer-controlled experimental system that interfaces biaxially uniform strain with electrical pacing, so that cellular deformation can be imposed during a specified phase o...

background: hypertension is a risk factor for many diseases. nutritional methods are considered as major tools in lifestyle modification for lowering blood pressure. the present study was conducted to determine the level of dietary adherence in hypertensive patients. methods: this descriptive-analytical study was performed in 2015, on hypertensive patients who were referred to heart clinic of s...

Background Diastolic function (DF) is not routinely assessed by cardiac MR (CMR), but is critical for assessment of common disease states such as heart failure or hypertrophy. At present, special pulse sequences (tagging, phase contrast) are necessary for CMR for diastolic function assessment. The purpose of this study was to assess cine CMR volumetric assessment of DF using a 3D modelbased ana...
