Introduction: There has been a continuous debate about the survival benefit of percutaneous coronary intervention (PCI) for the management of patients with stable coronary artery disease (CAD) and moderate to severe ischemia. To address this, we performed a meta-analysis of RCTs comparing PCI plus MT vs. MT alone in stable CAD patients to evaluate endpoints of all-cause mortality, cardiovascular (CV) mortality, and MI in a larger cohort of patients with objective evidence of myocardial ischemia. Methods: An electronic database search was conducted for RCTs that compared PCI on top of MT versus MT alone. A random effects model was used to calculate relative risk (RR) and 95% confidence intervals (CIs). Results: A total of 7 RCTs with 10,043 patients with a mean age of 62.54 ± 1.56 years and a median follow up of 3.9 years were identified. Among patients with (CAD) and moderate to severe ischemia by stress testing, PCI didn’t show any benefit for the primary outcome of all-cause mortality compared to MT(RR = 0.85; 95% CI 0.646-1.12; p= 0.639). There was also no benefit in cardiovascular (CV) death (RR = 0.88 ; 95% CI 0.71-1.09; p =0.18) or myocardial infarction (MI) (RR = 0.271 ; 95% CI 0.782-1.087; P =0.327) in the PCI group as compared to MT. Conclusions: Among patients with (CAD) and evidence of moderate to severe ischemia by stress testing, PCI on top of MT appears to add no mortality benefit as compared to with MT alone.

Abstract The impact of pre-existing depression on mortality in individuals with established coronary artery disease (CAD) remains unclear. We evaluate the clinical implications of pre-existing depression in patients who underwent percutaneous coronary intervention (PCI). Based on National Health Insurance claims data in Korea, patients without a known history of CAD who underwent PCI between 2013 and 2017 were enrolled. The study population was divided into patients with angina (n=50,256) or acute myocardial infarction (AMI; n=40,049). The primary endpoint, defined as all-cause death, was compared between the non-depression and depression groups using propensity score matching analysis. After propensity score matching, there were 4,262 and 2,346 matched pairs of patients with angina and AMI, respectively. During the follow-up period, there was no significant difference in the incidence of all-cause death in the angina (hazard ratio [HR] of depression, 1.013; 95% confidence interval [CI]: 0.893-1.151) and AMI (HR, 0.991; 95% CI: 0.865-1.136) groups. However, angina patients less than 65 years of age with depression had higher all-cause mortality (HR, 1.769; 95% CI: 1.240-2.525). In Korean patients undergoing PCI, pre-existing depression is not associated with poorer clinical outcomes. However, in younger patients with angina, depression is associated with higher all-cause mortality.

Multi-vessel coronary artery disease is quite a common state, which is often diagnosed by coronary angiography in patients with both stable coronary artery disease and acute coronary syndromes. Major difficulties in percutaneous coronary intervention include stent thrombosis and the need for antiplatelet therapy (aspirin and a P2Y12 inhibitor). Stent thrombosis leads to the recurrence of myocardial infarction and may occur within the first few hours after percutaneous coronary intervention. The use of dual antiplatelet therapy, especially that combined with low-molecular-weight heparin in the first days after myocardial infarction, poses a risk of bleeding, which often occurs in real clinical practice. Among P2Y12  inhibitors, ticagrelor causes bleeding somewhat more frequently than clopidogrel. A case of multi-vessel coronary artery disease is described in this paper. Coronary angiography revealed right-dominant circulation; occlusion of the proximal and medial segments of the right coronary artery, thrombolysis in myocardial infarction flow grade 0; stenosis of the left main coronary artery (50-60%), thrombolysis in myocardial infarction flow grade 2; diffuse stenosis of the medial and distal segments of the left anterior descending artery, thrombolysis in myocardial infarction flow grade 1; stenosis of the proximal segment of the left circumflex artery (> 75%), thrombolysis in myocardial infarction flow grade 1. The patient underwent percutaneous coronary intervention; the stents were implanted in the infarct-dependent right coronary artery. The clinical course was complicated by early stent thrombosis with subsequent thrombus extraction; a day later melena developed. Bleeding was stopped, the intensity of antithrombotic therapy was reduced: the combination of aspirin and ticagrelor was replaced by the combination of aspirin and clopidogrel. Six weeks after stenting of the infarct-dependent coronary artery, complete myocardial revascularization (hybrid intervention) was performed: coronary artery bypass grafting [the left internal mammary artery → the left anterior descending artery], coronary autogenous bypass grafting [the aorta → the right coronary artery and the aorta → the left circumflex artery]. The role of fractional flow reserve or instantaneous wave-free ratio-controlled complete myocardial revascularization techniques is discussed. The following algorithm for myocardial revascularization was used: percutaneous coronary intervention for the right coronary artery + coronary artery bypass grafting-3: the left internal mammary artery → the left anterior descending artery, the aorta → the left circumflex artery, the aorta → the right coronary artery.

Percutaneous coronary intervention is a well-established symptomatic therapy of stable coronary artery disease. Using a literature search with special emphasis on the newly-published FAME 2 trial data, the author wanted to explore why percutaneous coronary intervention fails to reduce mortality and myocardial infarction in stable coronary artery disease, as opposed to surgical revascularisation. In the FAME 2 trial, fractional flow reserve-guided percutaneous coronary intervention with second generation drug eluting stents showed a significant reduction in the primary composite endpoint of 2-year mortality, myocardial infarction and unplanned hospitalization with urgent revascularisation as compared to medical therapy alone. In addition, landmark analysis showed that after 8 days, mortality and myocardial infarction were significantly reduced. The author concludes that percutaneous coronary intervention involving fractional flow reserve guidance and modern stents offers symptomatic, as well as prognostic benefit. Orv.
