Percutaneous coronary intervention with stenting has become the most widely performed procedure for the treatment of obstructive coronary artery disease. But, a major drawback of coronary stenting is the occurrence of stent thrombosis. Though rare, stent thrombosis can lead to ST segment elevation myocardial infarction or even sudden cardiac death. This is a case of early coronary stent thrombosis in a 58-year-old male patient, who presented with acute chest pain, Mobitz type II 2:1atrioventricular block and cardiogenic shock 15 days after percutaneous coronary intervention with bare metal stenting to the right coronary artery.

Background: Aim of the study was to evaluate the primary procedural success of percutaneous coronary intervention of unprotected left main coronary artery stenosis using either Bare-metal stents or drug eluting stent. Methods: Total 33 patients were enrolled in this very preliminary non-randomized prospective cohort study. Among them, Male: 25 and Female: 8. Total 35 stents were deployed. Mean age were for Male: 59 yrs, for Female: 62 yrs. Associated coronary artery diseases risk factors were dyslipidemia, High Blood pressure, Diabetes Mellitus, Positive family history for coronary artery diseases and smoking. Results: Among the study group; 26 (78%) were Dyslipidemic, 24(70%) were hypertensive; 17 (51.5%) patients were Diabetic, 11(33%) were smoker and 7(21%) patients had family history of Ischaemic heart disease. Female patients were more obese (BMI M 26: F 27) and developed coronary artery diseases in advance age. Common stented territory were left main: 20 (60%), Left main to left anterior descending artery 7 (22%) and Left main to left circumflex artery 6 (18%). Average length and diameter of stent was 3.5 and 18 mm respectively. Stent used: Bare Metal Stent 5 (15%), Drug Eluting Stent: 28 (85%). Among the different Drug Eluting Stents, Everolimus eluting stents were 11 (39.3%), Sirolimus eluting 10(35.7%), Paclitaxel eluting 3 (10.7%), Biolimus eluting 3 (10.7%) and Zotarolimus eluting1 (3.6%). In the present study, overall survival outcome was 94% (31 patient), mortality of cardiac cause 3% (1 patient) and 1 patient (3%) died of hepatocellular carcinoma. Conclusion: Our study has shown that percutaneous coronary intervention of the unprotected left main is a safe and effective alternative to Coronary Artery Bypass Graft (CABG).

Artery Disease

Coronary artery disease (CAD) remains the leading cause of cardiovascular death in octogenarians. This group of patients represents nearly a fifth of all patients treated with percutaneous coronary intervention (PCI) in real-world practice. Octogenarians have multiple risk factors for CAD and often greater myocardial ischemia than younger counterparts, with a potential of an increased benefit from myocardial revascularization. Despite this, octogenarians are routinely under-treated and belittled in clinical trials. Age does make a difference to PCI outcomes in older people, but it is never the sole arbiter of any clinical decision, whether in relation to the heart or any other aspect of health. The decision when to perform revascularization in elderly patients and especially in octogenarians is complex and should consider the patient on an individual basis, with clarification of the goals of the therapy and the relative risks and benefits of performing the procedure. In ST-segment elevation myocardial infarction (MI), there is no upper age limit regarding urgent reperfusion and primary PCI must be the standard of care. In non-ST-segment elevation acute coronary syndromes, a strict conservative strategy must be avoided; whereas the use of a routine invasive strategy may reduce the occurrence of MI and need for revascularization at follow-up, with no established benefit in terms of mortality. In stable CAD patients, invasive therapy on top of the optimal medical therapy seems better in symptom relief and quality of life. This review summarizes the available data on percutaneous revascularization in the elderly patients and particularly in octogenarians, including practical considerations on PCI risk secondary to ageing physiology. We also analyse technical difficulties met when considering PCI in this cohort and the ongoing need for further studies to ameliorate risk stratification and eventually outcomes in these challenging patients.

Objective: To report a case of successful use of prasugrel following percutaneous coronary intervention with placement of a bare metal stent in a patient with a documented hypersensitivity reaction to clopidogrel. Case Summary: A 61-year-old male with a history of coronary artery disease with coronary stent placement presented with ST-elevation myocardial infarction. The patient had developed Stephens-Johnson syndrome 6 years earlier following Clopidogrel administration, characterized by erythematous plaques and subsequent desquamation of the hands and feet; Clopidogrel was discontinued and he was subsequently treated with ticlopidine in addition to aspirin. The third-generation thienopyridine prasugrel was initiated as a therapeutic alternative to Clopidogrel after placement of a bare metal stent; a 60-mg dose was administered after extubation, followed by 10 mg/day. No signs of allergic reaction were observed in the days, weeks, and months following administration. Discussion: Thienopyridines, specifically Clopidogrel, are the standard of care for prevention of coronary stent thrombosis; however, there are few data available on cross-hypersensitivity between these agents. One study demonstrated that 27% of patients who developed an allergic or hematologic reaction to Clopidogrel developed a similar reaction to ticlopidine. Other therapeutic options for patients with Clopidogrel hypersensitivity who are undergoing a percutaneous coronary intervention with stent placement include Clopidogrel desensitization, warfarin plus aspirin, cilostazol, ticagrelor, and ticlopidine. However, these options are limited by efficacy and/or toxicity. With its approval in 2009, prasugrel has become a potential treatment option. Conclusions: Prasugrel may be considered a therapeutic alternative in some patients allergic or intolerant to Clopidogrel, but additional data are warranted to make a strong conclusion.

Background: The role of thrombus aspiration plus primary percutaneous coronary intervention in ST-segment elevation myocardial infarction remains controversial. Methods: We performed a meta-analysis of 25 randomised controlled trials in which 21,740 ST-segment elevation myocardial infarction patients were randomly assigned to thrombus aspiration plus primary percutaneous coronary intervention or primary percutaneous coronary intervention. Study endpoints were: death, myocardial infarction, stent thrombosis and stroke. Results: On pooled analysis, the risk of death (4.3% vs. 4.8%, odds ratio (OR) 0.90, 95% confidence interval (CI) 0.79–1.03; P=0.123), myocardial infarction (2.4% vs. 2.5%, OR 0.95, 95% CI 0.80–1.13; P=0.57) and stent thrombosis (1.3% vs. 1.6%, OR 0.80, 95% CI 0.63–1.01; P=0.066) was similar between thrombus aspiration plus primary percutaneous coronary intervention and primary percutaneous coronary intervention. The risk of stroke was higher in the thrombus aspiration plus primary percutaneous coronary intervention than the primary percutaneous coronary intervention group (0.84% vs. 0.59%, OR 1.401, 95% CI 1.004–1.954; P=0.047). However, on sensitivity analysis after removing the TOTAL trial, thrombus aspiration plus primary percutaneous coronary intervention was not associated with an increased risk of stroke (OR 1.01, 95% CI 0.58–1.78). The weak association between thrombus aspiration and stroke was also confirmed by the fact that the lower bound of the 95% CI was slightly below unity after removing either the study by Kaltoft or the ITTI trial. There was no interaction between the main study results and follow-up, evidence of coronary thrombus, or study sample size. Conclusions: In patients with ST-segment elevation myocardial infarction, thrombus aspiration plus primary percutaneous coronary intervention does not reduce the risk of death, myocardial infarction or stent thrombosis. Thrombus aspiration plus primary percutaneous coronary intervention is associated with an increased risk of stroke; however, this latter finding appears weak.
