[Patients' symptoms before a first hospitalization due to Acute Coronary Syndrome].

The objective of this study was to characterize and compare patients regarding their report of experiencing chest pain, dyspnea and limitation of the daily life activities one week before their first hospitalization due to Acute Coronary Syndrome, according to the clinical presentation form, and compare them. This is a cross-sectional, descriptive and correlational study. A clinical evaluation instrument was used to investigate the presence and severity of dyspnea, chest pain and physical restriction due to myocardial ischemia. Regarding the limitation to carry out physical activities, patients diagnosed with unstable angina showed lower capacity the week before hospitalization, and reported experiencing dyspnea and chest pain more frequently than patients who had an infarction in situations ranging from making strong efforts, such as walking uphill or on a flat surface but very quickly, to resting and in situations of little effort.
