Abstract:
Objective To compare the effect of percutaneons coronary interventions (PCI) combined with polydanshinolate on myocardial reperfusion with PCI combined with regular medicine in patients with acute myocardi-al infrarction ,and whether polydanshinolate would decrease no-reflow,improve the myocardial micro-circulation and the ventricular remodeling and clinical end-point events at the sixth month. Methods Random,parallel control and prospective clinical design was used in the current study. Sixty eligible patients for PCI, who were diagnosed as first-time acute myocardial infrarction with ST stage increasing,were recruited in the study with informed consent. All par-ticipants were divided into two groups randomly. Group A was treated with PCI combined with polydanshinolate, group B was treated with PCI combined with regular medicine. The participants were followed up for six months. The resolution of the sum of ST segment elevation (sum STR) ,corrected TIMI frame count (CTFC) and myocardial con-trast echocardiography (MCE) were used to assess myocardial perfusion. Bleeding events, heart function and major adverse cardiac events (MACE) were observed during hospitalization and follow-up visit. Results No significant difference was observed between two groups on the clinical condition and the results of emergency CAG and PCI. Compared to group B,the incidence of TIMI grade 3 was significantly higher in group A (90.0% vs 63.3% ,χ~2 = 4.565, P=0.0326). Sum STR one hour after PCI in group A was siguificanfly higher than that in group B (80.0% vs 50.0%, χ~2=4.689, P=0.0304). CTFC after PCI also differed significantly between the two groups (24.1±8.3 vs 33.4±15.9 respectively,P=0.0062). Localized myocardial blood flow 48 hours after PCI showed no significant difference between the two groups (P>0.05), whereas both increased at the 7th day after PCI (5.85±1.26 vs 2.09±1.85,t=9.2008,P<0.0001 ;3.95±1.35 vs 1.95±1.29,t=5.8666,P<0.0001) ,and there were signifi-cant difference between the two groups (P<0.05). No significant difference of LVEF, LVEDV, LVESV were found between the two groups during the hospitalization and follow-up visit after 6 months (P>0.05). The incidences of cardiovascular events and severe heart failure during hospitalization and follow-up visit in group A were significantly lower than that in group B (P<0.05 ). Conclusions Polydanshinolate addition to PCI could reduce no reflow phe-nomenan in patients of acute myocardial infrarction, improve myocardial reperfusion, and furthermore, decrease cardi-ovascular events and ameliorate prognosis.
