Abstract
Background: Evaluation of diastolic dysfunction and its relationship with TIMI frame count in patients with stable coronary artery disease referred to Ayatollah Taleghani Hospital in Tehran in the years 2010-2011 is the purpose of this study.
Methods: Patients were divided into two groups: case and control. Both groups had chronic angina. Patient information on check list has been studies based on data provided by angiography and echocardiography methods.
Results: Cases had significantly higher values of corrected TIMI frame count (TFC) for the left anterior desending artery (LAD), TFC for Circumflex artery (Cx) & Right coronary artery (RCA), (mean TFC P<0.001). Conventional echocardiography showed significantly lower maximal peak systolic velocity (sm) (cm/s), Correlation of early diastolic velocity at myocardial segments (Em) & peak systolic velocity at myocardial segments (Sm) with mean TFC in all 3 vessels were significant (P=0/0001). Ratio of maximal early to late diastolic filling (E/A), in patient with TFC≥ 21 was 0/7 & in patients with TFC≤21 was 1. DT (Deceleration time) had no significant correlation with TFC. Mean of isovolumetric relaxation time (IVRT) in cases was 91 m/s & in controls was 72 m/s Which was higher in patients with mean TFC ≥21. Correlation between mean of angiography and diastolic disfunction was significant.
Conclusion: According to this study diastolic dysfunction which estimated by echocardiography showed significant correlation with TIMI frame count in chronic stable angina patients. Due to simplicity, low cost, quality and reproducibility of this method, this will be helpful.

Abstract
Background: Hypertension is an important and controllable risk factor for heart diseases, stroke, renal failure and peripheral vascular disease. The aim of this study was to determine the level of awareness of patients with hemorrhagic stroke to control blood pressure and to provide solutions to improve patients’ awareness.
Methods: This study is a descriptive cross-sectional study that was conducted to evaluate the knowledge of patients with hemorrhagic stroke about the use of antihypertensives. The study population consists of all patients with hemorrhagic stroke, who were admitted to the intensive care unit of Imam Hossein Hospital in Tehran from September 2020 to March 2021. Data related to blood pressure awareness and drug history was completed by the researcher through the method of direct contact with the patients or their relatives. In this study, 17 patients diagnosed with hemorrhagic stroke due to hypertension who were admitted to the intensive care unit of Imam Hossein Hospital in Tehran, were included. The extent of the exact treatment adherence was assessed using the Morisky questionnaire.

Results: In this study, the median of patients age was 67 and 10 (58.82%) of them were women. The median systolic and diastolic blood pressures were 170 and 95 mmHg on admission. 4(23.53%) subjects were not aware of the disease. Out of 13 people who were aware of their hypertension, 11(64.71%) were under the supervision of a physician. However, 7(63.64%) of the subjects, despite being under the supervision of a physician and acceptable drug adherence, did not have controlled blood pressure and expired.
Conclusion: This study is a warning for patients and health care providers to pay more attention to blood pressure control. Furthermore, educating the community as well as medical staff about the importance of timely diagnosis and accurate treatment of hypertension is highly recommended.
