Introduction: Myocardial ischemia in absence of angina pectoris is a metabolic phenomenon, consequence of decreased myocardial perfusion which is detected by contractile or electric disorders.

Objective: Screen asymtomatic myocardial ischemia in patients with coronary risk factors.

Method: Descriptive, cross-sectional and retrospective study in 50 patients older than 15 years, with more than 3 coronary risk factors and without chest pain or antecedents of cardiac ischemia who were assisted in the health clinic # 9 of Family Physician Plan belonging to "Rodolfo Ramirez" Polyclinic of Camagüey from January to December 1999. Electrocardiogram at rest and echocardiogram in modes M and B were performed and they were subjected to a maximal ergometry limited by symptoms.

Results: A 68% of patients were woman and 52% were among 46 to 60 years. Presented disorders at the st segment with effort suggesting myocardial ischemic 14%. Out of them, 100% were hypertensive, 86% smoked, and 73% had family history of cardiac ischemia, a 57% of diabetics was significant (p<0.01) and 28% with dyslipidemias (p=0.01); and only 14.2% presented ischemic disorders of the st-t in the electrocardiogram, left ventricular hypertrophy was significant (71%; p=0.04), different to contractility disorders (14.2%).

Conclusions: Asymptomatic myocardial ischemia is frequent in patients with 3 o more coronary risk factors, mainly if they are hypertensive, dyslipidemic, diabetic, smokers or have hypertrophy of the left ventricle shown.
