CLINICAL-EPIDEMIOLOGICAL STUDY ON STROKE PRESENCE IN THE POPULATION OF HERZEGOVINA-NERETVA CANTON INFLUENCED BY INVESTIGATED RISK FACTORS

The Cumulative Incidence of Stroke, Myocardial infarction, Heart Failure and Sudden Cardiac Death in Patients with Atrial Fibrillation

Introduction:

Atrial fibrillation represents the most common cardiac arrhythmia in clinical practice. By year 2030, 14–17 million AF patients are anticipated in the European Union. Atrial fibrillation remains one of the major causes of stroke, heart failure, sudden death all over the world.

Research Objectives:

The objective of our study is to determine the cardiac and cerebrovascular events (myocardial infarction, heart failure, stroke, sudden cardiac death) and their cumulative incidence during 11 years follow up period.

Patients and methods:

This study includes 2352 ambulant and hospitalized patients with atrial fibrillation (AF) who were enrolled during the follow up period. All patients underwent clinical evaluation in order to determine cardiac and cerebrovascular events (myocardial infarction, heart failure, stroke, sudden cardiac death) and their cumulative incidence.

Results:

The results of cumulative incidence for sudden cardiac death was 1.71%, for stroke 2.56%, for myocardial infarction 1.20% and for heart failure was 5.73%. In our study the age-adjusted incidence and prevalence of AF are slightly lower in women. The study shows that the risk of death is higher in females than in males with AF.

Conclusion:

Despite good progress in the management of patients with atrial fibrillation (AF), this arrhythmia remains one of the major causes of stroke, heart failure, sudden death. Effective treatment of patients with atrial fibrillation includes not only rate control, rhythm control, and prevention of stroke, but also management of cardiovascular risk factors and concomitant diseases.

Modified Algorithm for the Risk of Coronary Heart Disease Estimation

INTRODUCTION

Determination of the overall risk of coronary disease, enables the health professionals for planning the intensity of preventive action.

AIM

The aim of this study is that by the results obtained using a modified algorithm with tables adopted by the European Society of Cardiology demonstrate the possibilities for assessment of the risk of coronary heart disease degree, for application to the targeted individual or risk factors groups.

MATERIAL AND METHODS

The study was conducted as a retrospective, prospective and controlled (included two groups of 200 respondents).

RESULTS

By comparing the presence of risk factors according to the representation of groups of diseases, or myocardial infarction, results showed that the European and SCORE table have significantly lower levels of risk factors, or those with sustained myocardial infarction are ranked in groups of low and present risk in relation to our algorithm which patients with myocardial infarction ranked as high and pronounced degree of risk. Results showed that the European and SCORE table significantly reduce the levels of risk or the persons with heart failure have been ranked in the group of low and present risks in relation to our algorithm which patients with coronary insufficiency ranked as pronounced degree of risk.

CONCLUSION

Determination of the overall risk of coronary disease, enables the health professionals for planning the intensity of preventive action. The activities of primary prevention of risk factors, or already resulting disease, may be helpful in assessing the reduction in economic costs in healthcare, both due to lower morbidity, and reducing the total cost of treatment of patients with coronary disease.
