[Ischemic cardiomyopathy in Lome: epidemiologic aspects and risk factors (study of 461 cases)]

According to the WHO, cardiovascular disease such as arterial hypertension and ischemic heart disease will be the main non-communicable diseases in developing countries in the next decades. In Togo, there is no statistic on this disease on this day. Our objectives were to study the epidemiological aspects and to describe the risk factors of this affection in our surroundings. It is about a multicentric transverse study from June 1st, 2004 to May 31, 2007, in 3 sanitary formations of the city of Lomé.

The frequency of ischemic heart disease was 11, 46%. There was a feminine predominance with a sex-ratio of 0.71. The average age of the patients was about 55.3 +/- 13.4 years with extremes of 18 and 95 years. The cardiovascular risk factors were: dyslipidaemia (76.9%), hypertension (75.3%), left ventricular hypertrophy (72.8%), abdominal obesity (71.1%), hyperuricemia (50.5%), hyperglycemia (41.9%) of which overt diabetes (29%) and smoking (3%). There was a feminine predominance at the hypertensive and the obese. The women accumulated more modifiable risk factors than the men. The middle risk indication was of 2.34 +/- 0.9 at the men and 2.55 +/- 0.8 at the women. The different clinical forms were: stable angina (71.2%), unstable angina (1.7%) and myocardial infarction (5.2%); silent ischemia represented 21.9%. The antero-septal territory was the more reached in case of myocardial infarction and the antero-lateral territory in case of ischemia.

A sanitary politic centered on the eviction of the risk factors should help to reduce the prevalence of this affection for a long time in our surroundings.
