Introduction: The pulse pressure is an important marker and/or predictor of atherosclerotic cardiovascular accidents risks. Objective: To determine what relation there is between the pulse pressure and the myocardial acute infarction (MAI) in hypertensives and non-hypertensives, to establish observational criteria and the control of this component of blood pressure. Methods: A case-control, analytical and retrospective study was designed including a study group of 200 patients diagnosed with myocardial acute infarction, admitted in the Coronary Ward of the "Enrique Cabrera" Hospital during 2006-2007 and other control study in 200 patients admitted in Medicine Wards without cardiovascular disease excluding the diabetic a those aged under 30 according to a random selection. Study variables included: age, sex, smoking, systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), pulse pressure (PP) high blood pressure (HBP) and presence or not of myocardial infarction. Groups of pulse pressure = 50 mmHg and < 50 mmHg were created in hypertensive and non-hypertensive patients. Results: La myocardial infarction frequency in patients aged 30-39 was of 2 % and in the group aged over 60 or more, it was of 68,5%; the 54 % was of male sex, the HBP frequency was of 85,5 % and that of smokers of 51,5 % and with a PP = 50 mmHg, 76,0 %. The relation among SAP, DAP, MAP and HBP with the increase of pulse pressure (p = 0,000). The association of pulse pressure with MAI in hypertensive patients was significant with a OR 6,46 CI 95 % (3,72, 11,21) and in those non-hypertensive also it was significant with a OR 8,9 CI 95 % (3,51, 22,56). Conclusions: The pulse pressure may be a very useful tool in the observation, treatment and control of patients with MAI risk, both, in hypertensives and non-hypertensives.
