De-escalation of antianginal medications after successful chronic total occlusion percutaneous coronary intervention: Frequency and relationship with health status.

ABSTRACT: BACKGROUND:Successful chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can markedly reduce angina symptom burden, but many patients often remain on multiple antianginal medications (AAMs) after the procedure. It is unclear when, or if, AAMs can be de-escalated to prevent adverse effects or limit polypharmacy. We examined the association of de-escalation of AAMs after CTO PCI with long-term health status. METHODS:In a 12-center registry of consecutive CTO PCI patients, health status was assessed at 6?months after successful CTO PCI with the Seattle Angina Questionnaire and the Rose Dyspnea Scale. Among patients with technical CTO PCI success, we examined the association of AAM de-escalation with 6-month health status using multivariable models adjusting for revascularization completeness and predicted risk of post-PCI angina (using a validated risk model). We also examined predictors and variability of AAMs de-escalation. RESULTS:Of 669 patients with technical success of CTO PCI, AAMs were de-escalated in 276 (35.9%) patients at 1?month. Patients with AAM de-escalation reported similar angina and dyspnea rates at 6?months compared with those whose AAMs were reduced (any angina: 22.5% vs 20%, P?=?.43; any dyspnea: 51.8% vs 50.1%, P?=?.40). In a multivariable model adjusting for complete revascularization and predicted risk of post-PCI angina, de-escalation of AAMs at 1?month was not associated with an increased risk of angina, dyspnea, or worse health status at 6?months. CONCLUSIONS:Among patients with successful CTO PCI, de-escalation of AAMs occurred in about one-third of patients at 1?month and was not associated with worse long-term health status.

Project description:BACKGROUND:Percutaneous coronary intervention (PCI) is widely used in patients with chronic total occlusion (CTO), but its benefit in improving long-term outcomes is controversial. We aimed to develop a prediction score for grading "survival advantage" conferred by successful results of CTO-PCI and a scoring system for prediction of the influence of CTO-PCI results on major adverse cardiac and cerebrovascular events (MACCEs). METHODS:Follow-up data of 2625 patients who underwent CTO-PCI at 65 Japanese centers were analyzed. An integer scoring system was developed by including statistical effect modifiers on the association between successful CTO-PCI and one-year mortality. RESULTS:Follow-up at 12 months was completed in 2034 patients. During follow-up, 76 deaths (3.7%) occurred. Patients with successful CTO-PCI had a better one-year survival than patients with failed CTO-PCI (log rank P = 0.016). Effect modifiers for the association between successful procedure and one-year mortality included diabetes (P interaction = 0.043), multivessel disease (P interaction = 0.175), Canadian Cardiovascular Society class ?2 (P interaction = 0.088), and prior myocardial infarction (MI) (P interaction = 0.117). Each component was assigned a single point and summed to develop the scoring system. The patients were then categorized to specify the prediction of survival advantage by successful PCI: ?2 (normal) and ?3 (distinct). The differences in one-year mortality between patients with successful and failed treatment were -0.7% and 11.3% for normal and distinct score categories, respectively. In the scoring system for MACCE, score components were prior MI (P interaction = 0.19), left anterior descending artery (LAD)-CTO (P interaction = 0.079), and reattempt of CTO-PCI (P interaction = 0.18). The differences in one-year MACCEs between successful and failed patients for each score category (0, 1, and ?2) were -1.7%, 7.5%, and 15.1%, respectively. CONCLUSIONS:The novel scoring system assessing the advantage of successful PCI can be easily applied in patients with CTO. It is a valid instrument for clinical decision-making while assessing the survival advantage of CTO-PCI and the influence of procedural results on MACCEs.

Project description:BackgroundThe development of the technique has improved the success rate of percutaneous coronary intervention (PCI) for in-stent chronic total occlusion (IS-CTO). However, long-term outcomes remain unclear. The present study sought to investigate long-term outcomes of PCI for IS-CTO.MethodsA total of 474 IS-CTO patients were enrolled at two cardiac centers from 2015 to 2018 retrospectively. These patients were allocated into either successful or failed IS-CTO PCI groups. The primary endpoint (major adverse cardiac events [MACE]) consisted of recurrent angina pectoris (RAP), target-vessel myocardial infarction (MI), heart failure, cardiac death, or ischemia-driven target-vessel revascularization (TVR) at follow-up. Multivariable Cox regression analysis was used to investigate the association between treatment appropriateness and clinical outcomes.ResultsA total of 367 patients were successfully treated with IS-CTO PCI while 107 patients had failed recanalization. After a median follow-up of 30 months (interquartile range: 17-42 months), no significant difference was observed between the two groups for the following parameters: cardiac death (successful PCI vs. failed PCI: 0.9% vs. 2.7%; adjusted hazard ratio [HR]: 1.442; 95% confidence interval [CI]: 0.21-9.887; P = 0.709), RAP (successful PCI vs. failed PCI: 40.8% vs. 40.0%; adjusted HR: 1.025; 95% CI: 0.683-1.538; P = 0.905), heart failure (successful PCI vs. failed PCI: 6.1% vs. 2.7%; adjusted HR: 0.281; 95% CI: 0.065-1.206; P = 0.088), target-vessel related MI (successful PCI vs. failed PCI: 1.5% vs. 2.7%; adjusted HR: 1.150; 95% CI: 0.221-5.995; P = 0.868), MACE (successful PCI vs. failed PCI: 44.2% vs. 45.3%; adjusted HR: 1.052; 95% CI: 0.717-1.543; P = 0.797). More patients were free of angina in the successful IS-CTO PCI group compared with failed PCI in the first (80.4% vs. 60%, P < 0.01) and second years (73.3% vs. 60.0%, P = 0.02) following up. Successful IS-CTO PCI had a lower incidence of MACE in the first and second years (20.2% vs. 40.0%, P < 0.01; 27.9% vs. 41.3%, P = 0.023) compared with failed PCI. After a median follow-up of 30 months, the reocclusion rate was 28.5% and TVR was 26.1% in the successful IS-CTO PCI group. Receiving >18 months of dual antiplatelet therapy (DAPT) was an independent predictor of decreased risk of TVR (HR: 2.682; 95% CI: 1.295-5.578; P = 0.008) or MACE (without TVR) (HR: 1.898; 95% CI: 1.036-3.479; P = 0.038) in successful IS-CTO PCI.ConclusionsAfter a median follow-up of 30 months, the successful IS-CTO PCI group had MACE similar to that of the failed PCI group. However, the successful IS-CTO PCI group had improved angina symptoms and were free from requiring coronary artery bypass grafting in the first or second years. To decrease MACE, DAPT was found to be essential and recommended for at least 18 months for IS-CTO PCI.
