Objectives. Trimetazidine is an anti-ischemic medication licensed for the treatment of angina pectoris. However, the molecular mechanisms underlying its action remain incompletely elucidated. In this study, therefore, we examined the potential beneficial effects of trimetazidine on myocardial injury and endothelial dysfunction in patients with unstable angina in the perioperative period of percutaneous coronary intervention (PCI). Methods. A total of 97 patients with unstable angina were randomly divided into trimetazidine (n = 48) and control (n = 49) groups. All subjects received standard medical therapy. The trimetazidine group additionally received 20 mg trimetazidine three times daily 24 hours before and after PCI. Serum levels of creatine kinase-muscle/brain (CK-MB), cardiac troponin I (cTnI), heart-type fatty acid-binding protein (h-FABP), von Willebrand factor (vWF), and nitric oxide (NO) were measured before and the morning following PCI. Results. In the control group, levels of CK-MB, cTnI, and vWF were significantly elevated (P<0.05) and NO level was decreased after PCI (P<0.05). By contrast, no significant changes in the levels of these proteins were observed in the trimetazidine group after PCI (P>0.05). Moreover, h-FABP levels were not significantly altered after PCI whether in the control or in the trimetazidine group (P>0.05). Finally, a time-dependent increase in the levels of h-FABP from 0 to 6 hours after PCI, followed by a progressive decline, was observed (P<0.05). Conclusions. PCI induces endothelial dysfunction and myocardial damage in patients with unstable angina. Trimetazidine therapy in the perioperative period can reduce this damage.

Background: Ranolazine is a novel antianginal drug that reduces intracellular accumulation of calcium ion in ischemic myocardium. A pilot randomized study (n=70) has shown that pretreatment with ranolazine 1000mg twice daily for 7days significantly reduced periprocedural myocardial injury (PMI) in elective Percutaneous coronary intervention (PCI). Our objective was to detect whether similar effect could be obtained by ranolazine pretreatment through an interventional study. Materials & Methods: 110 patients with chronic stable angina scheduled for elective PCI were enrolled in an interventional study. For 7 days before the procedure, 55 patients were allocated to receive ranolazine 1000 mg twice daily (ranolazine group) and 55 patients didn't receive ranolazine (control group). Serum creatinine kinase-MB (CK-MB) and Troponin I levels were measured at baseline and 24 hours post procedure. Results: Periprocedural myocardial injury [i.e. an elevation of serum biomarkers (preferably cardiac troponins) above the 99th percentile of upper reference limit (URL)] was detected less commonly after PCI in ranolazine than in control group (11% vs. 27%, p=0.0001). Also, PCI-related myocardial infarction [i.e., post procedural increase in CK-MB>3 times above the URL] tended to be lower in the ranolazine versus placebo group: 1.8% versus 5.45%, P=0.0002. 24 hours post procedural levels of cardiac markers were also significantly lower in the ranolazine versus control group (CK-MB: 2.42±2.05 versus 7.02±9 ng/ml, P=0.001; Troponin 1: 0.447±0.74 versus 1.18±1.6 ng/ml, P=0.004). No significant adverse effect of the drug was reported. Conclusion: So, we have concluded that ranolazine was effective in significantly reducing the periprocedural myocardial injury in elective PCI.

Long Term Prognosis

Percutaneous Coronary Intervention (PCI) is the most commonly performed invasive therapeutic cardiac procedure and plays an important role in the treatment of ischemic heart disease. Complications of Percutaneous Coronary Intervention (PCI) are relatively infrequent. The most common complications include discomfort and bleeding at the puncture site where the catheter was inserted. Major complications include death, MI, or stroke and other infrequent complications include transient ischemic attacks (minor myocardial injury), vascular complication and contrast induced nephropathy, transient ischemia, or minor myocardial injury (MMI), myocardial necrosis due to compromisation of threatened coronary circulation during balloon inflation. Cardiac Troponin I (cTnI) assays for the assessment of myocardial injury has been demonstrated for the diagnosis of MMI and long term prognosis after PCI.Delta Med Col J. Jul 2017 5(2): 94-98

Pharmacological Preconditioning

Abstract Introduction Elective percutaneous coronary intervention (PCI) is accompanied by intraoperative ischemic myocardial injury (IIMI) up to 30% of the cases despite successfully performed procedure. Pharmacological preconditioning can prevent IIMI; Nicorandil is considered promising for this purpose. Purpose To study the possibility of pharmacological preconditioning by oral Nicorandil to ptevent ischaemic myocardial injury and 4a type myocardial infarction (MI) in patients with a stable form of coronary artery disease (CAD) before PCI. Material and methods 182 patients with CAD and indications for PCI were randomized into two groups: Nicorandil treatment group (additionally to β-blockers and a calcium channel blockers, n=90) and the control group (β-blockers and a calcium channel blockers, n=92). Nicorandil per os was prescribed 2 days before the PCI (30 mg/day); on the day of PCI – 2 hours before intervention (20 mg), 6–12 hours after PCI – 10 mg. The analysis of hs-Troponin I (hs-Tr) and creatine phosphokinase-MB (CK-MB)was carried out before PCI and 24, 72 hours after the procedure. The diagnosis of MI 4a type was established according to fourth universal definition. Double antiplatelet therapy was prescribed to all patients. Results Clinical profile (age, BMI, BP, creatinin clearance, LDL-cholesterol, glucose) of the patient groups were comparable by the basic parameters. The rate of hs-Tr after 24 hours has approached the 99th percentile from the upper limit of normal in 146 patients (80%). The increment of mean level of hs-Tr 24 hours after PCI has not distinguish statistically between the Nicorandil and the control group (364 vs 725 pg/ml, p=0,1). Mean of CK-MB increment in the control group has approached 2,5 ng/ml vs 0,5 ng/ml in the Nicorandil group (p=0.06). Among women (n=61), the increment of hs-Tr in 24 hours after PCI was statistically significantly lower (287 vs 1135 pg/ml, p=0,04) in the Nicorandil group compared to the control group. MI 4a type was detected in 12% of patients in the control group, and it decreased to 3% of patients in the Nicorandil group (p=0,05), it was observed in 21% in women in the control group and in 3% in the Nicorandil group. Conclusion Nicorandil treatment using before PCI decreases the risk of MI 4a in patients with a stable CAD due to the realization of pharmacological preconditioning.

Abstract Percutaneous coronary intervention (PCI) can cause myocardial injury or myocardial infarction. There is unmet need to reduce incidence or severity of PCI related myocardial injury or myocardial infarction. This study is to evaluate the protective effects of salvianolate on PCI related myocardial injury or myocardial infarction after elective PCI in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients. Methods We enrolled patients with NSTE-ACS who underwent elective PCI. The patients were randomly assigned to the salvianolate group or the control group. The incidence and the severity of PCI related myocardial injury or myocardial infarction, in addition to major adverse cardiac events (MACEs) during one year follow-up after PCI were studied between the two groups. We also performed a multivariate logistic regression analysis to determine the independent factors for PCI related myocardial injury or myocardial infarction after elective PCI. Results Compared with the control group, salvianolate treatment reduced the incidence of PCI related severe myocardial injury or myocardial infarction (11.7% vs 26.5%, p = 0.035). The rate of MACEs or all-cause death within one month or one year after the procedure was not significantly different between the two groups. Conclusions Periprocedural treatment with salvianolate reduces the incidence of PCI related severe myocardial injury or myocardial infarction, although it does not influence clinical prognosis.
