While risk assessment tools can aid in evaluating periprocedural complication risk, prevention and preparedness take precedence. Guided by the \"3 Ps\" framework-prevention, preparedness, and planning-we navigate the complexities of managing complications in CTO PCI procedures. This emphasizes the importance of comprehensive patient discussions, adherence to appropriateness use criteria, and ensuring a well-trained team equipped with standardized equipment. Furthermore, it is crucial to extract valuable insights from encountered complications, turning potential setbacks into invaluable learning opportunities. This positive approach not only fosters individual growth but also contributes to the advancement of CTO PCI practices. Various complications specific to CTO PCI are addressed, including donor vessel injury, equipment loss/entrapment, radiation injury and coronary perforation.</p>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal anticoagulation regimen in this clinical scenario is poorly defined. The present meta-analysis sought to investigate the efficacy and safety profile of direct oral anticoagulants (DOACs) compared with Vitamin K antagonists (VKAs) for the management of LV thrombus following AMI. A systematic literature review was conducted in electronic databases to identify studies reporting efficacy and safety outcome data regarding the use of DOACs versus VKAs for patients with LV thrombus after AMI. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated and random-effects meta-analyses were conducted to synthesize pooled ORs. Eight studies comprising a total of 605 patients were included. DOACs were associated with an almost 2-fold higher likelihood of thrombus resolution compared to VKAs (pooled OR 1.95 [1.25-3.04]; p =0.003, I² =0 %), and decreased the risk of systemic embolism by 70% (pooled OR 0.30 [0.12-0.75]; p =0.01, I² =0 %). The use of DOACs was associated with a 54% lower risk of bleeding compared to VKAs (pooled OR 0.46 [0.26-0.84]; p =0.01, I² =0 %). Overall, patients receiving DOACs had a 63% lower risk to reach the composite outcome of safety and efficacy compared with patients using VKAs (pooled OR 0.37 [0.23-0.60]; p <0.0001, I² =0 %).

Unmatched and propensity-matched (1:1) comparisons of clinical and echocardiographic outcomes were undertaken in SE and BE THVs along with Kaplan-Meier survival analysis. A total of 315 patients who underwent ViV-TAVR were included, of whom 73% received an SE THV. Median age was 77 years, and women comprised 42.5% of the population.

We performed a secondary analysis in Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) Trial participants who had coronary computed tomographic angiography (CTA) performed and Lp(a) data available. Lp(a) concentration was analyzed as a binary variable, with elevated Lp(a) defined as ≥50 mg/100 ml. “Stenosis ≥50%” was defined as ≥50% coronary artery stenosis in any epicardial vessel, and “stenosis ≥70%” was defined as ≥70% coronary artery stenosis in any epicardial vessel and/or ≥50% left main coronary artery stenosis. HRP was defined as presence of plaque on CTA imaging with evidence of positive remodeling, low computed tomography attenuation, or napkin-ring sign. Multivariate logistic regression models were constructed to evaluate the association between Lp(a) and the outcomes of obstructive CAD and HRP stratified by LDL-C ≥100 versus &lt;100 mg/100 ml.

We aimed to assess the proportion of the effect of hypertension (antihypertensive treatment) on incident HF to be eliminated by prevention of coronary heart disease (CHD) event treated with or without revascularization, considering possible treatment-mediator interaction. The causal mediation analysis of Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) included 42,418 participants (age 66.9 ± 7.7, 35.6% black, 53.2% men). A new CHD event (myocardial infarction or angina) that occurred after randomization but before the incident HF outcome was the mediator. Incident symptomatic congestive HF (CHF) and hospitalized/fatal HF (HHF) were the primary and secondary outcomes, respectively. Logistic regression (for mediator) and Cox proportional hazards regression (for outcome) were adjusted for demographics, cardiovascular disease history, and risk factors. During a median 4.5-year follow-up, 2,785 patients developed CHF, including 2,216 HHF events. Participants who developed CHD events had twice the higher incidence rate of CHF than CHD-free (28.5 vs 13.9 events/1,000 person-years). The proportion of reference interaction indicating direct harm because of a CHD event for lisinopril (234% for CHF, 355% for HHF) and amlodipine (244% for CHF, 468% for HHF) was greater than for chlortalidone (143% for CHF, 269% for HHF). In patients with revascularized CHD events, chlortalidone and amlodipine eliminated 21% to 24% and lisinopril eliminated −45% of HHF. Antihypertensive treatment could not eliminate harm from CHD events treated without revascularization. In conclusion, the antihypertensive drugs (chlortalidone, lisinopril, and amlodipine) prevent HF not principally by preventing CHD events but by way of other pathways. HF is moderated but not mediated by CHD events. Revascularization of CHD events is paramount for HF prevention.</p></div>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142144968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
