[Our results with the secondary prevention of myocardial infarct].
The communication summed up the results from the two prospective follow-up care-prophylactic studies on patients with a past history of acute myocardial infarction (AMI). The first study covers all patients, with a past history of AMI and discharged in 1963, 1964, 1966 and 1967, a total of 378, with a follow-up period from 6 to 11 years. The direct task of the follow up was the prevention of a repeated infarction. The prophylactic measures, carried out with the followed-up patients were: control of body mass by a hypocaloric and antisclerotic diet, sufficient physical activity and medicamentous treatment when needed. Two groups of patients were differentiated: experimental (the patients adhering to the instructions prescribed) an control (patients that did not adhere to the recommendations for correction of body mass with no motor regimen). After the termination of the observation it was established that 12.6% from the experimental group had repeated infarction and 28.3%--in the control group. The lethality in the experimental group was 21.7% and in the control--43.9%. The second prospective observation covered 250 patients (reduced to 241 in time), with a past history of AMI and discharged within the year 1975. The follow up lasted for 5 years under the same conditions of follow-up care. Summing up our 5-year secondary prophylaxis carried out mainly with a diet, physical activity and partially with antiaggregants and medicamentous treatment when needed, we could ascertain and draw the conclusions.(ABSTRACT TRUNCATED AT 250 WORDS)
