We carried out an economical study on a period of four years from august 2001 to june 2005 in 100 patients with acute myocardial infarction admitted in the intensive care unit and in the medicine department of the Abidjan Cardiology institute. The aim of this study was to evaluate the total cost of an hospitalisation for myocardial infarction in a sub-saharan country. The average estimated cost was 944 481 F CFA (1439.7 euros) (range: 105,4237.7 euros) This cost was mainly explained by medical treatment with 324,996 F CFA, being 34.4% of the mean total cost followed by the cost of bedroom (300,200 F CFA (31.8%) and explorations costs (31.8%). 55% of our patients spent more than one million for the treatment. Neither the siege nor the appearance of left ventricular insufficiency had any incidence on the cost.
