The prevalence of coronary artery disease (CAD) is increasing in Iran. Patients with depression who have a myocardial infarction are more likely to die and patients who have depressive symptoms during hospitalization may have increased cardiovascular events. This study aimed to determine the relationship between anxiety, depression and coronary artery disease among patients undergoing angiography in Ghaem Hospital, Mashhad. This was a case-control study conducted between September 2011 and August 2012 among patients undergoing coronary angiography in Ghaem Hospital, Mashhad, Iran. There were 486 cases that were found to have one or more coronary stenoses, with a stenosis of equal or more than 50% of the diameter of at least one major coronary artery. The other patient group consisted of the patients in whom the coronary artery stenosis was less than 50% in diameter which was classified as angiography negative, and a control group that consisted of 440 healthy adults aged 18 years old and above who were selected among people who attended for routine medical checkup and medical examination of employment. The dependent variables were Beck Anxiety and Depression Inventory scores and the independent factors were coronary artery disease, and socioeconomic profiles. Validated and reliability-tested questionnaires were used for data collection. The mean age of patients was 55.75 ± 10.64 years and in the healthy group was 55.83 ± 8.55 years; there was no significant difference in age between subject groups (p = 0.897) nor a significant difference in the gender frequency distribution of subjects (p = 0.610). There was a significant difference in anxiety score between the Angio positive and Angio negative patients and healthy control subjects (p < 0.001). There was a statistical significant difference between groups for the anxiety score (p < 0.001). However, the subjects did not differ significantly for BDI depression score (p = 0.534). A significant positive relationship was found between anxiety score and depression score when data were analyzed by Pearson’s test (p < 0.001, Pearson’s correlation = 0.582). Depression and anxiety are associated among patients with CAD undergoing coronary angiography sessions.

1. Introduction

Coronary artery disease (CAD) is a major problem globally and it is more hazardous for men than for women. The statistic mortality shows that 34% men and 28% women die because of this problem. CAD has a number of risk determinants, such as lifestyle, psychological factors, environment [1] [2] , age, emotional status, and smoking [3] . CAD is the end-point of a chronic and progressive condition that leads to heart failure and death [4] [5] .

Depression and anxiety are also common disorders within all populations [3] , but few studies have paid attention to the influences of depression and anxiety on physical health [6] . Anxiety sensitivity (AS) is different for each person since the symptoms concerning fear are associated with anxiety arousal, and anxiety has negative somatic signs and to a larger extent affects those who are psychologically vulnerable, such as those with depression and depressive symptoms [7] . Studies show that women have a higher prevalence of these symptoms than men [3] .

We know that there is an association between depression and physical health and it is thought to be an important risk factor for heart diseases [8] , and mood state has been identified as a determinant of quality of life in those who have coronary disease [9] . One out of every five patients with coronary patients has depression symptoms [6] [10] [11] . CAD reduces the life quality of the patient, for example, performance of life activities, ability to use medication and diet therapies [10] . The degree of depression and anxiety is associated with a greater decline in physical functioning of patient with heart failure [6] . Depression and anxiety appear to be highly overlapping with each other and they cause an increased risk more than 80% of CVD following when adjusted for CAD risk factors [12] , but we should know that depression and coronary heart diseases are reversible, and coronary heart diseases may lead to depression [13] .

Recently studies have shown that patients with depression who have myocardial infarction are more likely to die and the patients who have depressive symptom during hospitalization probably have increased cardiovascular events [8] [14] . Mood state may lead to hospitalization even after correction for demographic and medical factors [6] . Many studies have reported that mood disorders have an important impact on the outcome of cardiac transplantation; depressed patients with heart transplant have a tendency to be less active than those without [15] [16] . Social support is an important factor of psychology and it is useful for influence on heart, for example, patients with heart failure who are unmarried or seldom visit their family or friends have a significantly higher risk of serious impairment in activities [6] . To our knowledge, there are a few data to look at the association between mood status and CAD; therefore, we hope to investigate the association between anxiety and depression in CAD potions based on angiography.

2. Methods & Materials

2.1. Participants and Procedure

Coronary angiograms were undertaken using routine procedures and were performed by a specialist cardiologist. These patients who undergoing coronary angiography, especially for stable angina, and at least as more as one object test of myocardial ischemia such as Dobutamin stress or exercise stress test [17] . 486 patients (247 males and 239 females) were recruited for this study. Patients were selected from adult (>18 years of age). All subjects were without a past clinical history of angiography and heart surgery. The subjects consisted of three groups, patients group and healthy group (control group). The patients were classified into two groups. The first group consisted of the patients whose result of angiography shows one or more stenosis with the occlusion of >50% of the diameter of at least one major coronary artery and so they would be considered as a significant angiography positive (case group). And the second group consists of the patients in whom the coronary artery stenosis was <50% in diameter which is classified as not having significant (angiography negative) [18] -[20] . 440 healthy (231 males and 209 females) from adult (beyond the age of 18) who were selected among people who come for routine medical checkup and employment Medical examination at employment.

All subject full the questionnaires about physical and mental health functioning, smoking, depression, and anxiety test. This study focused on overlapping CAD, depression, and anxiety.

2.2. Anthropometric and Other Measurements

Anthropometric measurements for each subject including height, weight, by using standard protocols were done. The calculation of body mass index (BMI) was performed as weight (Kg) divided by height squared (m2) [21] .

2.3. Assessment of Depression and Anxiety

The Beck Anxiety Inventory (BAI) is a 21-questionstion multiple-choice self-report inventory that is used for measuring the severity of an individual’s anxiety [22] . It assesses two factors: somatic, that applied 12 items explaining physiological symptoms, such as, “numbness or tingling”, “feeling dizzy or lightheaded” and subjective anxiety and panic, that applied the remaining 9 items of the BAI measures, such as “fear of the worst happening” and “unable to relax” [22] . According to the Anxiety beck questioner score, if a person get 7 or less from this test has minimal anxiety, mild anxiety score is 8 - 15 and moderate anxiety is 16 - 25 and more than 25 is severe anxiety [23] [24] . The Beck Depression Inventory (BDI) is 21-item; self-report rating inventory the measurement of characteristic attitudes and symptoms of depression was done by the Beck. Beck developed a triad of negative cognitions about the world, the future and the self which play a major role in depression. If a person get 15 or less from this test has no depression, mild depression is 16 - 30, moderate depression, score is 31 - 46 and severe depression, is more than 47 [24] . These questioners were given to subjects before any procedures.

2.4. Statistical Analysis

Statistical analysis were used the Statistical Package for Social Sciences version 16. Descriptive statistics (frequency, mean, standard deviation) determined for all variables. Differences in coronary artery stenos is (Angio− or Angio+) were analyzed by the chi-square test for categorical variables. We used categorical depression and anxiety base on score of them. Multivariate analyses were used to examine effects of demographic variable (such as weight, Height, BMI) on coronary artery disease.

3. Results

Nine hundred and twenty six subjects were evaluated for depression and anxiety. Four hundred and eighty six persons had a history of cardiac signs or symptoms and 440 persons were healthy subjects. The mean age of all subjects were 55.79 ± 9.65 years old and there was no significant difference between patients and healthy subjects (p = 0.897) also no statistical significant difference were found in gender of subjects between groups (p = 0.610) (Table 1).

When subjects were divided into patient and healthy subjects there was a statistical significant difference between groups in anxiety score (p < 0.001). But the subjects had no significant difference in depression score assessed by the BDI (p = 0.534) (Table 1).

A significant statistical effect of gender on depression scores was found for healthy and patient groups (p < 0.001) (Table 2).

As shown in Table 3, there was a significant difference between angiography positive, negative and healthy subjects in anxiety score and also in the number of persons who had minimal anxiety (p < 0.001). Other category of anxiety score (mild, moderate and severe) had no difference among three groups (p > 0.05) (Table 3).

According to that the angiography results subjects can be divided according to the number of involved coronary vessels. Depression and anxiety scores results in Table 4 based on the number of vessels involved are shown. Again, there were significant differences in anxiety among groups. After post HOC test were performed significant difference was found between healthy and angiography negative group (p < 0.001).

In this study a significant direct linear correlation was found between anxiety score and depression score when data were analyzed by Pearson test (p < 0.001, Pearson correlation = 0.582) (Figure 1). This correlation either found in healthy and patients group.

4. Discussion

Depression is one of the main risk factors, which leads to morbidity and mortality resulted from coronary artery disease (CAD). Depressed persons with initially good medical health have an elevated incidence of CHD. In addition, the risk of mortality is increased in people who are depressed after myocardial infarction (MI). Another important point is that depression is also associated with elevated expression of inflammatory biomarkers [25] .

According to a recent meta-analysis, perceived stress is associated with the risk of coronary artery disease [26] . Individuals with anxiety disorders or depressed mood are prone to unhealthier lifestyle [27] . This lifestyle might lead to increased cardiovascular risk factors, associated with for example inactivity, smoking, unhealthy nutrition [27] .

Figure 1. Correlation between anxiety and depression score in healthy and patient group.

In this study 926 healthy and suspected to cardiovascular disease subjects were tested for depression and anxiety by Beck questionnaire. The results of these tests showed that the anxiety is associated with CAD and the angiography positive or negative persons (subjects who had cardiovascular sign and symptoms) had high incidence of anxiety so that the anxiety score and subjects that have minimal anxiety are significant difference between groups (p < 0.05). Same findings were reported in some other studies [25] [28] [29] .

In Lindeberg’s study “exhaustion predicted CHD in both men and women, but its independence from depression and anxiety was demonstrated only in men” [3] an according to Table 2, significant difference found between healthy and patients subjects in gender and depression.

Although there is no significant difference between depression score in healthy and patients group but there is statistical significant difference were observed between depression and no depression categories (no < 15 and yes >15) among groups (p < 0.05) (Table 3) and also there were a good linear correlation found between anxiety and depression score (Figure 1) this correlation are found in both healthy and patient group.

Patients who suffered from severe depression probably have no adequate emotional activity for participate to any researches so it is one of our limitations. Process of in Table 2 shows that emotional desire in research participation is loss.

5. Conclusion

In conclusion, depression and anxiety Beck scores have great correlation in healthy and CAD patients. We found a good association between anxiety and angiography positive, angiography negative and healthy subjects. So psychiatry visits by specialties in cardiovascular patients are recommended for case fining in depression mood and anxiety disorder.
