Anxiety and decreased nervousness tolerance are among the main problems of coronary heart disease patients that can make negative physiological and psychological consequences. Therefore, the aim of this study was to determine the effectiveness of cognitive-behavioral therapy in anxiety and distress tolerance in patients with coronary heart disease.

In a quasi-experimental study with a pretest-posttest design with a control group with follow-up period, from the statistical population that included of all patients with coronary artery disease referred to the specialized center of Shahid Lavasani Hospital in Tehran in the summer of 2021, 30 volunteers were selected by purposive sampling and then randomly divided into two experimental and control groups (15 people in each group). The research instruments included Beck et al.'s (1988) Anxiety Inventory and Simmons and Gaher (2005) Anxiety Behavior Questionnaires, which were administered to both groups as pretest, posttest, and follow-up. Alice and Beck cognitive-behavioral therapy was performed in ten 90-minute sessions for the experimental group, but the control group received the usual treatment. Data were analyzed using repeated measures analysis of variance and SPSS software version 16 at a significance level of 0.05.

The results showed that there was a significant difference between the experimental and control groups in the post-test in anxiety variables (p <0.001) and anxiety tolerance components (p <0.001). Also, the results were stable in the follow-up period (p <0.001).

According to the results, cognitive-behavioral therapy was effective in reducing anxiety and increasing anxiety tolerance in patients with coronary heart disease. Therefore, it can be used as a complementary treatment along with medical methods to improve the psychological status (reduce anxiety and increase distress tolerance) in patients with coronary heart disease.

Coronary artery disease is one of the most progressive diseases in society, the negative consequences of which affect the mental health of women as one of the most important members of the family and society; Therefore, psychological therapies can be an opportunity without negative consequences in their mental repair. The aim of this study was to determine the effectiveness of metacognitive therapy in comparison with positive therapy on depressive symptoms, psychological well-being and purpose in life.

The research method is quasi-experimental and is a pretest-posttest design with a control group. The statistical population includes female patients referred to Dr. Pourabrahim's office who had coronary artery occlusion and are available using sampling method. The collection tool includes a questionnaire and a protocol.

The results showed that metacognitive and positive therapies are effective on depressive symptoms, psychological well-being and purpose in life. Metacognitive therapy differs from positive therapy in psychological well-being. There is a difference between metacognitive therapy and positive goal-oriented therapy in life.

Therefore, it is concluded that according to the obtained averages, metacognitive treatment has a greater impact on the symptoms of depression and psychological well-being and purpose in the life of women with coronary artery disease, and this requires more attention of trustees to strengthen And the use of therapies in the psychological improvement of patients.

Clinical disorder of coronary artery disease is mainly due to atherosclerosis of coronary arteries. The process of atherosclerosis is an inflammatory response to endothelial damage of the artery wall. Biomechanical factors and hemodynamic damages are the main causes of endothelial tissue damage. The spread of atherosclerosis can lead to destruction and sometimes loss of heart function. The purpose of the current study was to provide a systematic review of the studies conducted to investigate the effect of exercise rehabilitation on the coronary artery biomechanical variables of atherosclerotic patients.

In the present study, after a thorough search among relevant articles published in reliable databases such as Science Direct, Elsevier, PubMed, Springer, SID and Magiran published between 1998-2018 in two English and Persian languages using the terms exercise rehabilitation, biomechanics, atherosclerosis, and coronary arteries, a total of 38 articles with direct relevance to the subject under the study were selected for the analysis.

A review of the findings in these studies suggests that, due to the occurrence of atherosclerosis, the structure of vascular wall and the nature of its constituent parts become hard and thick. In addition, with the development of atherosclerosis, blood flow changes from a laminar state to turbulent one. Mechanical forces on the vascular wall, including shearing stresses of blood flow on the lumen of vessel and the peripheral stresses due to blood pressure, with the advancement of atherosclerotic lesions, change the pattern and add to the severity of disease. Studies have shown that the effects of exercise rehabilitation on atherosclerotic patients include morphological changes that lead to improved blood flow. Increased shear stress levels due to exercise result in decreased vascular resistance and increased tissue perfusion, reduced arterial stiffness, increased vasodilation capacity, increased artery lumen diameter, increased proliferation of atherosclerotic plaque, and improved angiogenesis and arteriogenesis. Exercise rehabilitation reduces disability, reduces the need for interventional procedures, improves cardiovascular risk factors profile, improves the new myocardial vessels formation, reduces mortality, and improves quality of life. In addition, combined exercises (aerobic-resistance) are also superior to aerobic exercises or resistance exercises alone.

According to the results, exercise rehabilitation, while preventing the development of atherosclerosis and protecting against major cardiovascular events, improves all coronary artery biomechanical variables and patients are in a relatively stable condition. In addition, all studies support that point that the exercises should be performed regularly and preferably during the week with high moderate intensity and in combination.

Coronary artery disease (CAD) is the Non-contagious leading cause of mortality worldwide, as more than 1 million heart attacks and strokes occur every year, of which about 30% of them die. The use of invasive methods such as angiography for the diagnosis of coronary artery disease has been reached with high costs due to the cost of this method and its complications, and on the other hand, non-invasive methods such as echocardiography is more cost-effective and has fewer side effects.

This descriptive retrospective cross-sectional study was performed in selected hospitals in Yazd in the second six months of 2014. All cases were collected from patients admitted for angiography and echocardiography, and in total 1801 records/files were submitted for examination.

Assessment of patient’s records indicated, the echocardiography results in 38% of patients and exercise test results in 30% of the patients and the result of the angiography in 72% of patients, were abnormal .

The results showed that, 38% of the echocardiographic results and 72% of the angiographic results were abnormal. Performing non-invasive tests, such as echocardiography and exercise testing, resulted in a loss of cost due to a small number of positive cases and also may cause an anxious in patients. This result has been shown more likely in women and young individuals.
