Unstable angina (UA) is situated in a spectrum with myocardial infarction (MI) at one end of it and stable angina at the other end. To determine the clinical and paraclinical characteristics of unstable angina this study was designed.
Materials and Methods: Two hundred patients with definite UA who were hospitalized at cardiac care units (CCU) in Yazd were enrolled in this cross- sectional study. Clinical and para-clinical characteristics including class of severity of angina, clinical circumstances, drugs, risk factors, changes in ECG, and patient's condition at the time of leaving hospital were evaluated.
Results& Conclusions: The average of age of patients was 61.85 years and 57% of them were female and 43% were male. The most prevalent risk factor among men was smoking (48.8%) and among women was hypertension (62.8%). According to Braunwald suggestion, patients were divided into 3 classes based on the severity of their diseases. Frequency distribution of patients in classes I,H and III were 24.5%, 4% and 71.5%, respectively. Normal ECG, was observed in 24.5% of subjects at the time of hospitalization and in 67% of patients when leaving hospitals. Frequency distribution based on the risk stratification was 22.5%, 58.5% and 19% in the low, medium and high risk groups, respectively. During hospitalization, acute myocardial infarction (AMI) was seen in 3.5% of individuals that majority of them belonged to class III of angina.
