Abstract
The clinical outcome after PCI depend on various factors including; cardiac function assessed by different echocardiographic parameters, complexity of CAD assessed mainly by SYNTAX score, associated comorbidities (i.e HTN, DM, dyslipidemia) and compliance of patients to post PCI medications (antiplatelets, statin, beta-blokers, angiotensin –system inhibitors). The aim of this study is to compare the value of both Tei index and SS in prediction of clinical outcome after PCI. Our study included 100 patients with stable ischemic heart disease who were referred and subjected to elective PCI at Mansoura Specialized Medical Hospital catheterization laboratory from December 2016 to January 2018. After PCI, patients was evaluated after one week, one month and 3 months. Evaluation was done by direct contact with patients or through phone for assessing disappearance and degree of chest pain and Occurrence of any Major Adverse Cardiac Events (SCD, MI, stroke, target vessel revascularization). Results: Follow up of patients for 3 months revealed that; 82 % of patients improved at 1 week and 1 month follow up but only 75 % of patients showed improvement at 3 months follow up. 3 patients developed MI before 3 months. No patients developed stroke, SCD or subjected to target vessel revascularization. Improvement of anginal pain after PCI has significant correlation with HTN and SS. Improvement has no significant correlation with any other demographic parameters, risk factors (age, DM, dyslipidemia, smoking and family history of CAD), other echocardiographic parameters (LV systolic function, DD, RSWMA and MR) or angiographic features such as number and type of affected vessels. No significant correlation between improvement and Tei index or patient compliance to post PCI medications. Angiotensin system inhibitors was associated with less improvement of angina pain after PCI. No significant correlation between Tei index and SS. Tei index has significant correlation with age, ischemic changes in resting ECG and Doppler assessed LV DD. Tei index has no significant correlation with any other demographic parameters, risk factors (DM, HTN, dyslipidemia, smoking and family history of CAD), other echocardiographic parameters (LV systolic function, MR, RSWMA) or angiographic features such as number and type of affected vessels. In conclusion: No significant correlation between Tei index and improvement of chest pain or development of MACE after PCI. SYNTAX score can predict improvement of patients after PCI. Most patients improved after PCI especially those with low SS, non hypertensive and who did not receive angiotensin system inhibitors
