EFFECT OF INTERVENTION ON THE CONTROL OF RISK FACTORS IN CORONARY ARTERY DISEASE PATIENTS

Objective: to assess the effect of optimal medical therapy on the control of risk factors in coronary arterydisease (cad) patients with or with-out intervention.methodology: it was a cross sectional comparative study carried out at lady reading hospital, peshawarjanuary to december 2010. subjects were divided into two groups based on percutaneous coronaryintervention and optimal medical therapy. study variables were smoking, physical activity, dyslipidemia,diabetes, hypertension and obesity. informed written consent was taken from all the study participants.data was recorded on a preformed questionnaire and analyzed with spss version 16. p-value of 0.05 wastaken as significant.results: a total of 315 patients were studied. baseline characteristic were similar between groups.smoking was decreased significantly in(pci group) as compared to (omt group) (p=0.027). physicalactivity goal . 150 min/ week were achieved more in (pci group) compared to (omt group)(p=0.019).goals set for serum cholesterol, hba1c%, serum ldl, systolic blood pressure and diastolic bloodpressure have significantly achieved in (pci group) as compared to (omt group) with p- valves of(0.018,0.027,0.023,0.033 and 0.017) respectively. while goals set for triglycerides, serum hdl and bmihave no significant difference between the two groups with p-valves of (0.223, 0.089 and 0.164respectively).conclusion: patients who underwent intervention and remained on optimal medical therapy were moreadherent to regular exercise and good compliance which lead to better risk factors control for coronaryartery disease as compared to patients who remained on optimal medical therapy alone.
