Objective: Multimorbidity in elderly patients increases complications and retards the recovery of pulmonary function after coronary artery bypass grafting (CABG) surgery. We aimed to evaluate the impact of multiple-intervention pulmonary rehabilitation (PR) on respiratory muscle strength and dyspnea scores after CABG in adult patients aged ≥65 years who had multimorbidity.

Methods: A cohort study was retrospectively conducted with 95 adults aged ≥65 years who underwent CABG surgery and completed a multiple-intervention PR program.

Results: Patients in the non-multimorbidity ( = 56) and multimorbidity groups ( = 39) were evaluated on the basis of their muscle strength, degree of dyspnea, and pulmonary function. Postoperative complications were compared after the completion of PR. Between extubation days 1 and 14, the multimorbidity group showed significant improvements in maximal inspiratory pressure (16.91 vs. 24.95 cmHO, < 0.001), Borg Scale score (0.99 vs. 2.3, < 0.001), and the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV/FVC ratio) of 7.02% vs. 13.4% ( = 0.01). The incidence rates of pulmonary complications were similar between the two groups.

Conclusions: Multi-interventional PR program significantly improved the maximal inspiratory pressure, Borg scale score, and FEV/FVC ratio in the adult patients aged ≥65 years who had multimorbidity after undergoing CABG surgery.

Background: Despite the advances in the last decades for treatment of ischemic heart disease, women continue to experience poorer prognosis than men and currently, there is a gap in knowledge regarding the optimal revascularization strategy in women.

Objective: Compare the long-term outcomes of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for the treatment of stable ischemic heart disease in women.

Methods: A systematic search was conducted including randomized clinical trials (RCTs) comparing PCI with drug-eluting stents with CABG.

Risk factors of delirium after cardiac surgery: a systematic review and meta-analysis.

J Cardiothorac Surg

December 2024

Cardiovascular Medicine Department, Shengjing Hospital of China Medical University, Shenyang City, Liaoning Province, 110004, China.

Background: Post-operative delirium (POD) is a relatively common occurrence following surgical procedures, particularly cardiac surgeries. Given that the majority of pharmacologic treatments for delirium have demonstrated inadequate efficacy, it is of great importance to identify risk factors to prevent delirium or reduce its complications. Consequently, in this systematic review and meta-analysis, we identified risk factors of POD after cardiac surgery.

Objective: Diffuse coronary artery disease remains a critical issue that heart surgeons continue to research in terms of treatment options. An alternative method applied during coronary bypass surgery to achieve complete revascularization is coronary artery endarterectomy. Since the reliability of this technique and its effects on mortality and morbidity are still debated in the literature.

NSTEMI and Ischemic Mitral Regurgitation: Incidence and Long-Term Clinical Outcomes with Respect to Management Strategy.

Arq Bras Cardiol

Department of Research, U. N. Mehta Institute of Cardiology and Research Centre (UNMICRC), Civil Hospital Campus, Gujarat - Índia.

Background: The optimal treatment for ischemic mitral regurgitation (IMR) in patients of non-ST elevation myocardial infarction (NSTEMI) is a debated topic.

Objective: To evaluate the long term outcome on patients with NSTEMI and IMR, particularly emphasizing the comparison of treatments in those with moderate to severe MR.

Methods: We enrolled patients with NSTEMI and classified non/trivial to mild regurgitation as insignificant IMR and moderate to severe regurgitation as significant IMR.

Background: With the increase in the number of coronary artery bypass grafting (CABG) surgeries, the concern about complications after it has also increased. RV diastolic dysfunction (RVDD) is one of the post-CABG complications, and in this study, we intend to investigate its frequency and predictors.

Methods: In this cross-sectional study, eighty CABG candidate adult patients were included.
