Aims: The timely selection of severe heart failure (HF) patients for cardiac transplantation and advanced HF therapy is challenging. Peak oxygen consumption (VO2) values obtained by the cardiopulmonary exercise testing are used to determine the transplant recipient list. This study reassessed the prognostic predictability of peak VO2 and compared it with the Heart Failure Survival Score (HFSS) in the modern optimized guideline‐directed medical therapy (GDMT) era. Methods and results: We retrospectively selected 377 acute HF patients discharged from the hospital. The primary outcome was a composite of all‐cause mortality, or urgent cardiac transplantation. We divided these patients into the more GDMT (two or more types of GDMT) and less GDMT groups (fewer than two types of GDMT) and compared the performance of their peak VO2 and HFSS in predicting primary outcomes. The median follow‐up period was 3.3 years. The primary outcome occurred in 57 participants. Peak VO2 outperformed HFSS when predicting 1 year (0.81 vs. 0.61; P = 0.017) and 2 year (0.78 vs. 0.58; P < 0.001) major outcomes. The cutoff peak VO2 for predicting a 20% risk of a major outcome within 2 years was 10.2 (11.8–7.0) for the total cohort. Multivariate Cox regression analyses showed that peak VO2, sodium, previous implantable cardioverter defibrillator (ICD) implantation, and estimated glomerular filtration rate were significant predictors of major outcomes. Conclusions: Optimizing the cutoff value of peak VO2 is required in the current GDMT era for advanced HF therapy. Other clinical factors such as ICD use, hyponatraemia, and chronic kidney disease could also be used to predict poor prognosis. The improvement of resource allocation and patient outcomes could be achieved by careful selection of appropriate patients for advanced HF therapies, such as cardiac transplantation.

Background: Patients with chronic kidney disease (CKD) experience atrial fibrillation more frequently. The balance of medical management for stroke prevention and bleeding events presents a challenging issue in CKD population. Left atrial appendage occlusion (LAAO) may be an effective solution for stroke prevention in patients who experience frequent bleeding with oral anticoagulants. However, the specific impact of CKD on the procedural success, complications, and outcomes of LAAO implantations remains underexplored., Methods: We conducted a search of various databases for articles published before October 31, 2023. This search yielded 7 studies, comparing outcomes between CKD and non-CKD cohorts undergoing LAAO implantation. Our analysis focused on CHA2DS2-VASc scores, average eGFR, use of oral anticoagulants, procedural success rates, procedural complications, and associated outcomes., Results: The meta-analysis included data from 2576 patients, with 1131 identified as having CKD. The CKD group also had higher CHA2DS2-VASc scores (4.7 ± 1.4 vs 4.0 ± 1.5; P < .001) and HAS-BLED scores (3.8 ± 1.1 vs 3.1 ± 1.0; P < .001) than the non-CKD group. CKD patients showed a nonreduction in procedural success rates and a nonsignificant increase in total complications. The risks of stroke and transient ischemic attack, major bleeding, and cardiovascular mortality were not significantly different between the 2 groups. However, a significantly lower rate of total mortality was observed in the non-CKD group (odds ratio: 0.43; 95% confidence interval, 0.32-0.60)., Conclusion: While CKD is associated with a nonsignificant decrease in procedural success and a nonsignificant increase in complication risks, the outcomes of LAAO implantation are comparably favorable between CKD and non-CKD groups. Despite similar procedural outcomes, the CKD group exhibited a higher rate of all-cause mortality., Competing Interests: The authors have no funding and conflicts of interest to disclose.

Background: Few studies have investigated the clinical efficacy and pulmonary side effects of different P2Y12 inhibitors in acute coronary syndrome (ACS) patients. The aim of this study was to explore the impact of forced expiratory volume in 1 second over forced vital capacity (FEV1/FVC) ratio on the clinical outcomes in ACS patients treated with dual antiplatelet therapy after percutaneous coronary intervention (PCI)., Methods: ACS patients who underwent PCI, had documented pre-existing spirometry tests, and received aspirin with either ticagrelor or clopidogrel were enrolled for retrospective analysis., Results: Of the enrolled ACS patients, 275 and 247 received ticagrelor and clopidogrel, respectively. The incidence of wheeze was significantly higher in the ticagrelor group compared to the clopidogrel group within 360 days (14.91% vs. 8.09%, p = 0.016). Multivariable analysis revealed that ticagrelor treatment, as compared to clopidogrel treatment, independently predicted 1-year hospitalization for acute exacerbation (AE) of obstructive airway disease (hazard ratio: 3.44; 95% confidence interval: 1.92 to 6.15; p < 0.01). The receiver operating characteristic curve indicated that an FEV1/FVC ratio of 63.85% had the highest sensitivity and specificity for predicting the incidence of AE of obstructive airway disease within 1 year (p < 0.001). The 1-year hospitalization rate for AE of obstructive airway disease was significantly higher in the ticagrelor group when the FEV1/FVC ratio was < 63%., Conclusions: This study demonstrated higher incidence of wheeze and hospitalization for AE of obstructive airway disease in ACS patients treated with ticagrelor compared to clopidogrel. Furthermore, the FEV1/FVC ratio ≤ 63% in the ACS patients predicted hospitalization for AE of obstructive airway disease in 1 year.

Background: In patients with end-stage renal disease (ESRD), acute myocardial infarction (AMI) increases the risks of cardiovascular events, death, and bleeding. Several scores have been developed for predicting ischemic and bleeding outcomes in AMI patients, but none have been validated specifically for ESRD patients., Objectives: To compare and validate different risk scores as predictors of ischemic and bleeding outcomes in AMI patients with ESRD., Methods: This retrospective study enrolled 340 patients who had received percutaneous coronary intervention for AMI while undergoing maintenance hemodialysis for ESRD. Ischemic risk scores (TIMI-STEMI, TIMI-NSTEMI, GRACE, DAPT) and bleeding risk scores (PRECISE-DAPT, CRUSADE, ACUITY, ACTION, SWEDEHEART) were calculated. The ischemic outcome mainly focused on major adverse cardiovascular events (MACEs) within 14 days after hospitalization, and the bleeding outcome was 14-day major bleeding according to the CRUSADE criteria., Results: The GRACE score was superior in discriminating ischemic outcomes, especially in 14-day MACEs [area under curve (AUC) 0.791, p < 0.001]. None of the scores could ideally discriminate 14-day CRUSADE major bleeding, while the PRECISE- DAPT score had the best discriminative power (AUC 0.636, p < 0.001). Either GRACE score > 222 or PRECISE-DAPT score > 48 was associated with higher net adverse cardiovascular events (a composite of 14-day MACEs and 14-day CRUSADE major bleeding)., Conclusions: In AMI patients with ESRD, the GRACE score can effectively discriminate the risk of short-term ischemic events. None of the scores could ideally discriminate the bleeding risk, but a high PRECISE-DAPT score still represented a higher rate of bleeding events.

Background: Controlling modifiable risk factors (MRFs) in patients with cardiovascular diseases has been shown to be effective in reducing re-hospitalization rates. The aim of this study was to investigate the rates of controlled MRFs and clinical outcomes after pharmacist interventions in patients with myocardial infarction (MI) after hospital discharge., Methods: This prospective randomized clinical study was conducted at one medical center in Taiwan, and enrolled patients with MI from January 1, 2012 to December 31, 2014. Patients received medication reconciliation and education from a pharmacist before hospital discharge. The intervention group (IG) received continuous consultations from the pharmacist after discharge, whereas the control group (CG) did not. Primary outcomes included achieving blood pressure < 140/70 mmHg, low-density lipoprotein-cholesterol (LDL-C) < 70 mg/dL, and hemoglobin A1c (HbA1c) < 7% targets. The secondary outcome was major adverse cardiac events (MACEs), defined as re-hospitalization due to MI, unstable angina and stroke., Results: Two hundred and eight patients completed the study protocol (106 in the IG and 102 in the CG). The rate of achieving blood pressure goal was similar between the two groups. More patients in the IG achieved LDL-C and HbA1c goals than those in the CG at 1 year and 2 years post discharge. However, there was no significant difference in the cumulative incidence of MACEs between the two groups (5.7% vs. 9.8%) (p = 0.262). Diabetes was the only independent predictor of re-hospitalization due to a MACE., Conclusions: Pharmacist interventions led to a higher rate of optimal controlled MRFs but did not significantly reduce the MACE rate in the patients with MI.
