1. MYOCARDIAL PERFORMANCE INDEX COMBINED WITH FRAMINGHAM CORONARY HEART DISEASE RISK SCORE IN DETERMINING ANGIOGRAPHIC SEVERITY OF CORONARY ARTERY DISEASE BY GENSINI SCORING Jennifer Doria-del Castillo PERPETUAL SUCCOUR HOSPITAL – CEBU HEART INSTITUTE

2. BACKGROUND OF THE STUDY FRAMINGHAM CHD RISK SCORE MYOCARDIAL PERFORMANCE INDEX GENSINI SCORE RISK PROGNOSTICATOR OF FUTURE CV EVENTS ECHO MEASURE OF SYSTOLIC & DIASTOLIC FUNCTION VALIDATED MEASURE OF ANGIOGRAPHIC SEVERITYOF CAD SIMPLE & NON INVASIVE REPRODUCIBLE INDEPENDENT OF LV GEOMETRY

3. RESEARCH QUESTION: Can Myocardial Performance Index combined with Framingham Coronary Heart Disease Risk Score determine angiographic severity of coronary artery disease assessed by Gensini scoring?

4. GENERAL OBJECTIVE : To investigate whether Myocardial Performance Index when combined with Framingham Risk Score determine angiographic severity of Coronary Artery Disease

5. SPECIFIC OBJECTIVES: • To describe the clinical and demographic profile of the subjects • To determine the Framingham Coronary Heart Disease Risk Score of the patients prior to coronary angiography • To determine the Myocardial Performance Index by 2DEchocardiography of the patients prior to coronary angiography

6. SPECIFIC OBJECTIVES: 4. To determine the proportion of patients with significant obstructive coronary artery disease among patients who underwent coronary angiogram 5. To determine the angiographic severity of coronary artery disease by Gensini scoring 6. To compare the Framingham Coronary Heart Disease Risk Score and Myocardial Performance Index between patients with significant coronary artery disease and with insignificant coronary artery disease 7. To determine correlation between Myocardial Performance Index and angiographic severity of coronary artery disease by Gensini Score 8. To determine correlation between Myocardial performance Index combined with Framingham Coronary Heart Disease Risk Score in the assessment of angiographic severity by Gensini scoring

7. METHODOLOGY • Study Design: prospective , analytical cross sectional study • Study Setting: Perpetual Succour Hospital- Cebu Heart Institute , a private , tertiary hospital with a 250 bed capacity located in Cebu City with cardiac specialty units • Study Period: June 2011 – February 2012

8. STUDY POPULATION: N= 71 INCLUSION CRITERIA: • CAD suspects • 2Dechocardiography • Coronary angiogram EXCLUSION CRITERIA: • Atrial Flutter • Atrial fibrillation • Bundle branch blocks • Valvular Heart Disease

9. ASSESSMENT OF RISK FACTORS - Framingham Coronary Heart Disease Risk Factors Blood pressure Smoking status Diabetes mellitus Lipid levels ( total cholesterol and HDL levels) - On line analysis* • Classified based on the National Cholesterol Education Program/Adult Treatment Panel III for 10 yr risk of Coronary Heart Disease into 3 categories a. low risk for score <10% b. intermediate risk for 11-20% c. and high risk for >20%.3 *http://www.mdcalc.com/framingham-coronary-heart-disease-risk-score-si-units

10. GE Vivid 7 • Complete Standard • Echo Study • MPI = sum of interventricular contraction time and relaxation time divided by ejection time • MPI = ICT + IRT • Ejection Time • Myocardial Performance Index= a –b • b

12. STATISTICAL ANALYSIS Descriptive statistics : mean ± SD age and body mass index Categorical variables: frequency and percentage smoking , alcohol consumption, diabetes , dyslipidemia Continuous Variables : mean ± SD

13. STATISTICAL ANALYSIS FOR THE TEST OF INFERENCES : Chi square test of independence and Fischer Exact Test: categorical variables Pearson r product Moment Correlation: continuous variables Multiple Regression : partial and combined correlations among Framingham Coronary Heart Disease Risk score and Myocardial performance index in predicting Gensini scores. p-value lesser than 0.05 alpha level considered significant

21. CORRELATION OF FRAMINGHAM CHD RISK SCORE WITH GENSINI SCORING FRAMINGHAM CHD RISK SCORE r = 0.118, p = 0.332 GENSINI SCORE

22. CORRELATION OF MYOCARDIAL PERFORMANCE INDEX WITH GENSINI SCORING MYOCARDIAL PERFORMANCE INDEX r = 0.444, p = 0.000 GENSINI SCORE

23. FITTED MODEL PLOT OF THE COMBINED FRAMINGHAM CHD RISK SCORE AND MPI WITH THE GENSINI SCORE

24. CONCLUSIONS: FRAMINGHAM RISK SCORE NO significant correlation with GENSINI SCORE (r = 0.118, p = 0.332) MYOCARDIAL PERFORMANCE INDEX Moderate Correlation with GENSINI SCORE (r = 0.444, p = 0.00) FRAMINGHAM RISK SCORE + MYOCARDIAL PERFORMANCE INDEX SLIGHT TO MODERATE POSITIVE ADD ON CORRELATION (20%) TO GENSINI SCORE (R = 0.199)
