ABSTRACT

Objective:

Ventricular rhythm disorders which after myocardial infarction has a negative effect on the prognosis. We studied 49 patients with one or more episodes of ventricular tachycardia (VT) lasting longer than 30 seconds, less than fifteen days after myocardial infarction. In our study we research the factors determining the risk of mortality in the five-year follow-up of these patients.

Material and Methods:

All patients consisted of cases who presented with VT attack after discharge. Programmed ventricular stimulation, late potential examination (LP) and rhythm Holter follow-up were performed to all patients. Holter and LP analyzes were performed at 6-month intervals in the follow-up for 5 years, and PSV was performed in the first 3 months.

Results:

Forty four men and five women, 49 patients who had myocardial infarction constitute the study group. The average age is 55 (between 33 and 79). Seventeen cases died during the study period, 10 of them were due to heart disease. Low left ventricular ejection fraction is one of the determining factors in high mortality. If left ventricular ejection fraction was less than 35% the five-year survival was 67%, and if the left ventricular ejection fraction was greater than 35%, the five-year survival was 80%. Anterior myocardial infarction has a higher mortality rate than inferior myocardial infarction. However, in our study, the difference was not found as significant. In treatment types comparison, treatment with amiodarone or different antiarrhythmic drug or ablation, there was no statistically significant difference neither.

Conclusion:

Due to the small number of patients in our study, we think, further studies with larger patient groups are needed.
