RESUMO

Perceived health state assessment has been a fundamental research theme in health, as its results contribute to define treatments, assess the cost/benefit of care and reduce morbidity/mortality rates. This research aimed to: compare the presence of symptoms, the perceived health state and the severity degree of depression according to the diagnosis of Acute Coronary Syndrome (ACS): Acute Myocardial Infarction (AMI) versus Unstable Angina (UA); investigate the presence of possible relations between perceived health state and the severity degree of depression in the two groups and analyze the variance in the perceived health state and the severity degree of depression measure explained by predictive variables. Study descriptive, correlational and cross-sectional, developed at the Coronary Unit and cardiology wards of two public hospitals in the interior of São Paulo, Brazil. The researcher held individual interviews, collecting sociodemographic and clinical characterization data and applying a questionnaire on ACS-associated symptoms, an instrument to assess the perceived health state (SF-36) and depression (Beck Depression Inventory). Data were analyzed using the association test (Chi-square), Students t-test for independent samples and Pearsons correlation test. Five multiple linear regression models were constructed to verify the variance percentages explained by each of the predictive variables. The significance level was set at 0.05. Research participants were 253 patients, 142 of whom were diagnosed with AMI, with an average age of 55.8 years and mostly men (74.6%). In the UA group (111 patients), the average age was 60.6 years and patients were mostly male (62.2%) too. With regard to the perceived health state, the best assessments came from patients victims of AMI, who also presented minor severity degree of depression when compared with UA patients. Negative correlations were observed between perceived health state and the severity degree of depression in both patient groups, which were weak to strong in the infarction group and moderate to strong in the angina group, all statistically significant. Using gender, age, presence of previous treatments for cardiovascular diseases and ACS manifestations as predictive variables, adjusted R2 levels amounted to 0.138; 0.231; 0.129 and 0.117 for Physical Aspects, Functional Capacity, Pain and Emotional Aspects, respectively. The inclusion of the depression measure and the use of psychotropic drugs raised levels to 0.251; 0.349; 0.259 and 0.263, all statistically significant increases. With regard to the model constructed for depression, using the same predictive variables as in earlier models, the adjusted R2 was 0.149. In conclusion, all SF-36 domains were more committed among patients with UA than among patients with AMI. UA patients also reported higher severity degree of depression more frequently. Moreover, patients with higher severity degree of depression presented worse assessments of the perceived health state.
