ABSTRACT
Acute myocardical infarction [AMI] in young patients has different characteristics from that in older. The purpose of the present study was to assess the risk factors, presenting symptoms, features of coronary angiographic [CAG] and echocardiographic findings, complications and in-hospital mortality of young patients with AMI in a referred teaching heart center compared with those of older patients. A descriptive-analytic study was conducted involving 100 young [35 years and below] and 100 older [over 35years] patients with clinical diagnosis of AMI. The differences in the risk factors, clinical characteristics and CAG and echocardiographic findings were analyzed between the two groups between January 2000 and September 2009. Compared with the older patients, the risk factor of positive family history was more frequently found among the young patients. Hypertension and diabetes mellitus were more prevalent risk factors in non-young patients. Smoking and Dyslipidemia [DLP] were prevalent risk factors in the both. In the young patients low-density lipoprotein cholesterol [LDLC], the levels of erythrocyte sedimentation rate [ESR], and white blood cell [WBC] count were significantly higher, while lower high-density lipoprotein cholesterol [HDL-C] and higher BUN were found in the elderly patients. Echocardiographic findings showed lower LVEF in older patients. Angiography identified higher incidence of no-vessel or one-vessel disease in the young patients [43.8% vs. 30.1%]. Young patients with M I had lower morbidity rate than older patients with the same mortality. Positive family history is the major risk factor rather than smoking and dyslipidemia for AMI among individuals below the age of thirty five, who often have milder coronary artery stenosis than elderly patients. Alcoholism as a social habit is more highlighted prevalent in the young adult MI. Young patients seems to have lower morbidity, with the same mortality
ABSTRACT
Primary cardiac tumors are rare and occur in 1 per 1000 to 1 per I00000 individual in unselected autopsy series at tertiary heart centers .Approximately 75% of cardiac tumors are histologically benign and malignant cardiac tumors are reminder of them. We describe a rare form of complicated benign cardiac mass in 46 years old man
ABSTRACT
To determine the predictive value of flow-mediated vasodilation [FMD] compared with angina pectoris, exercise electrocardiography, and myocardial perfusion imaging [MPI]. This study was carried out in Shahid Madani Heart Center, Tabriz, Iran from April 2004 to September 2006. A total of 92 patients with chest pain syndrome were enrolled in this study. Using high resolution ultrasound system endothelial function was evaluated, and the result of the flow-mediated dilation [FMD%] was defined as the percent change in the internal diameter of the brachial artery during reactive hyperemia related to baseline. Coronary artery disease [CAD] was documented in 77 [83.7%] patients. The percentage of FMD was lower in patients with CAD compared with those without it [3.55 +/- 3.71 versus 10.76 +/- 4.61,P=0.001]. In comparison with typical anginal chest pain [sensitivity 46.7%, specificity 80%], exercise stress test [sensitivity 75%, specificity 60%], and MPI [sensitivity 96.5, specificity 55.6%] the receiver operator characteristic curve showed the percentage FMD optimal cut-off value as
