Mediating Role of Social Support on the Relationship among Depression Perceive Stress, Stressful Life Event and Cardiovascular Diseases

Study was designed to examine the relationship between well-being and environmental factors and their influence on cardiovascular disease. Cross sectional and co-relational research design were adopted. Data was collected over a span of 04 months from Multan Institute of Cardiology (MIC) and from the cardiology ward 1-A Nishtar Hospital Multan. A purposive sample of 200 cardiovascular patients was requested to provide information regarding stressful life events, perceived stress, depression, social support and cardiovascular diseases. Sample of 200 cardiovascular patients consisted of 100 males and 100 females. Independent sample t-test, ANOVA as well as PLS-SEM (structural equation modeling) was used to examine the hypothesis.  Results informed about the positive impact of psychological stressors on cardiovascular diseases which was partly mediated by social support, because social support effect the way CVD patients perceives the stress full events as well as decrease the threshold of psychological stressors. It was concluded that psychological stressors (Depression, Perceived stress, Stressful life events) and low social support increases the severity of cardiovascular diseases within a short duration among cardiovascular patients. Patients with mild psychological stressors and high social support sustain a milder form of CVD disease e.g. Hypertension for longer time duration without shifting to sever form of cardiovascular diseases while on the other hand contrary happen in the case of high   level of psychological stressors and lower level of social support.
