conclusions diagnosing type d personality and knowing about the effect of these perceptions can help physician to identify patients with prone personality and prevent them from the disease by changing their lifestyle. results ninety-nine chd patients, with the mean age of 59.7 years (age range, 20 - 86) were studied and 58.8% of them were males. cronbach’s alpha for quality of life and type d p...

Cardiovascular disease is the leading cause of death worldwide, and coronary artery disease (CAD) is the most common type of heart disease. Up to 20–30% of patients presenting with chest discomfort demonstrate no signs of obstructive CAD. In the field of invasive cardiology more than 50% of the patients undergoing coronary angiography for non-acute chest pain have normal or near normal coronary...

In patients suspected of having coronary artery disease (CAD), noninvasive testing has been playing an increasing role in selecting patients who would require coronary angiography for either the "definitive" diagnosis of CAD or as a prelude to planning myocardial revascularization. A mathematic model is presented that defines cost-effective utility of nuclear cardiology testing for diagnosis of...

background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...

conclusions the coronary sinus flow per minute is the most accurate parameter among the three echocardiographic parameters mentioned above for the assessment of significant stenosis of the coronary artery. results flow (ml/minute), flow/lvm (ml/minuteg) and lv (d-s) mass a-l all correlated significantly with the percentage of stenosis (r = -0.64, p < 0.001; r = -0.47, p < 0.001; r = -0.56, p < ...

Background: It has been demonstrated that free oxygen radicals have a close interaction with lipid peroxidation, causing a modification of low-density lipoproteins (LDL) and facilitating LDL deposition, with the consequent formation of atherosclerosis plaques. Free radical production is catalyzed and accelerated in the presence of iron. This study was conducted to evaluate the possible associ...

the possibility that infectious agents may trigger a cascade of reactions leading to inflammation, atherogenesis and vascular thrombotic events has recently been raised. chlamydia pneumoniae is an infectious agent that has received the most attention with respect to coronary artery disease (cad). to determine the relationship between c. pneumoniae and cad, a case control study was conducted on ...

background: the existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (cad). however, the results of the studies conducted hitherto on this subject are inconsistent. we sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of cad in patients undergoing n...

Background HIV infection is associated with an increased likelihood of coronary artery disease (CAD) and related events, but the underlying mechanisms are not well understood. Reduced coronary distensibility (CD) may contribute to the development of atherosclerosis and is present in CAD patients. While aortic distensibility (AD) is known to be reduced in HIV, CD in HIV patients has not been stu...

BACKGROUND Hyperhomocysteinemia has recently been identified as a risk factor for coronary artery disease. Some genetic variants (such as C677T polymorphism) are postulated in this regard. We studied the relation between hyperhomocysteinemia and the above genetic variant and risk of coronary artery disease (CAD) and also the number of involved vessels. MATERIALS AND METHODS From a total of 90...
