Background: Current guideline recommendations encourage culprit vessel only percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease. However, recent studies have shown a better clinical outcome in patients who receive multivessel PCI.
Aim: To measure and compare clinical outcomes between partial revascularization (PR) versus complete revascularization (CR) in patients with STEMI and multivessel disease who underwent a cardiac rehabilitation programme.
Methods: We retrospectively reviewed the medical records of 282 patients with STEMI and multivessel disease who received PR or CR and were subsequently enrolled in a cardiac rehabilitation programme between July 2006 and November 2013 at La Paz University Hospital. The incidences of cardiovascular events, new PCI, hospital admissions for cardiovascular reasons and mortality were compared between the PR and CR groups.
Results: Overall, 143 patients received PR and 139 received CR. Baseline characteristics were similar in both groups, except for mean age (59.3 vs. 56.7 years; P=0.02), diabetes mellitus prevalence (34.3% vs. 20.1%; P=0.01) and number of arteries with stenosis (2.6 vs. 2.3; P=0.001). During the mean follow-up of 48.0±25.9 months, a cardiovascular event occurred in 23 (16.1%) PR patients and 20 (14.4%) CR patients, with no statistically significant differences in the early (hazard ratio: 0.61, 95% confidence interval: 0.19-1.89) or late (hazard ratio: 1.40, 95% confidence interval: 0.62-3.14) follow-up periods. Cox regression, adjusted for age, sex, presence of diabetes mellitus and number of affected coronary vessels, showed no difference in new cardiovascular event risk.
Conclusions: There were no statistical differences in clinical outcomes between PR and CR among patients who received cardiac rehabilitation.

Impella versus Non-Impella for Non-emergent High-Risk Percutaneous Coronary Intervention: Impella vs. Non-Impella for HR-PCI.

Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).
Minimal extra-cardiac atherosclerosis present in young people with sudden cardiac death due to coronary artery disease.

Aim: To define the association between severe coronary artery disease and widespread atherosclerosis in younger individuals.
Methods: Individuals aged 1-50 years with sudden cardiac death (SCD) from 2019-23, autopsy-proven to be due to coronary artery disease, were identified using the state-wide EndUCD registry. Presence of extra-coronary atherosclerosis greater than modified American Heart Association class III was assessed in 5 arterial beds (intra-cerebral vessels, aorta, carotid, renal and femoral arteries).
Physiology-Versus Angiography-Guided Complete Coronary Revascularization in STEMI Patients with Multivessel Disease: A Network Meta-Analysis.

: In patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), complete revascularization (CR) is recommended over culprit-only PCI to reduce adverse cardiovascular outcomes. However, the optimal strategy for CR, whether angiography (Angio)-guided or physiology-guided, remains uncertain. : This network meta-analysis included 14 randomized controlled trials (RCTs) with 11,568 patients to compare the efficacy of angio-guided CR, physiology-guided CR, and culprit-only PCI in reducing major adverse cardiovascular events (MACE), all-cause mortality, recurrent myocardial infarction (MI), cardiovascular (CV) death, and unplanned revascularization.

Over the past decades, new treatments and guidelines have been introduced for the screening and management of familial hypercholesterolemia (FH). However, the impact of these medical and scientific advances on the characteristics and burden of coronary lesions over time in FH remains poorly documented. The primary goal of this study is to determine the characteristics of coronary lesions in HeFH patients who underwent coronary angiography within two distinct timeframes: the last five years versus those who had the procedure at the same hospital 25 years earlier.

Objective: Cardiopulmonary bypass (CPB) via the right axillary artery (RAA) has become an alternative perfusion strategy, especially in complex aortic procedures. This study delineates our technique and outcome with direct axillary cannulation utilizing the Seldinger technique, which we adopted as the standard perfusion strategy in the sternum-sparing minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) using CPB.
Methods: From November 2019 to December 2023, a total of 413 consecutive patients underwent nonemergent isolated coronary artery bypass grafting (CABG) via left anterior minithoracotomy on CPB with peripheral cannulation via the RAA and cardioplegic cardiac arrest, using this technique as a default strategy in the daily routine.
