Aims: There were no previous studies comparing aspirin versus P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after complex percutaneous coronary intervention (PCI).

Methods And Results: We conducted a prespecified subgroup analysis based on complex PCI in the 1-year results of the STOPDAPT-3 trial, which randomly compared 1-month DAPT followed by aspirin monotherapy (aspirin group) to 1-month prasugrel monotherapy followed by clopidogrel monotherapy (clopidogrel group). The main analysis in the present study was the 30-day landmark analysis.

The Role of Imaging in Pulmonary Vascular Disease: The Clinician's Perspective.

Radiol Clin North Am

March 2025

Department of Medicine, UT Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-8558, USA; Department of Pediatrics, UT Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-8558, USA. Electronic address:

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

Department of Radiology and Biomedical Imaging, University of California San Francisco, M-391 Box 0628, 505 Parnassus Avenue, San Francisco, CA 94143, USA.

Pulmonary hypertension is a rare but important clinical problem that presents a sometimes challenging diagnostic dilemma. The diagnosis of pulmonary hypertension relies on a combination of clinical testing and radiologic imaging, with chest computed tomography (CT) often serving as the primary imaging modality for comprehensive evaluation of the chest. Chest CT can be used to evaluate for causes of pulmonary hypertension including chronic lung disease, pulmonary artery obstruction, and congenital heart disease.

Background: The Scottish Computed Tomography of the Heart (SCOT-HEART) trial demonstrated that management guided by coronary CT angiography (CCTA) improved the diagnosis, management, and outcome of patients with stable chest pain. We aimed to assess whether CCTA-guided care results in sustained long-term improvements in management and outcomes.

Methods: SCOT-HEART was an open-label, multicentre, parallel group trial for which patients were recruited from 12 outpatient cardiology chest pain clinics across Scotland.

Background: The associations of early-onset coronary heart disease (CHD) and genetic susceptibility with incident dementia and brain white matter hyperintensity (WMH) remain unclear. Elucidation of this problem could promote understanding of the neurocognitive impact of early-onset CHD and provide suggestions for the prevention of dementia.

Objectives: This study aimed to investigate whether observed and genetically predicted early-onset CHD were related to subsequent dementia and WMH volume.

Background: Cardiovascular risk factors (CRFs) like hypertension, high cholesterol, and diabetes mellitus are increasingly linked to cognitive decline and dementia, especially in cerebral small vessel disease (cSVD). White matter hyperintensities (WMH) are closely associated with cognitive impairment, but the mechanisms behind their development remain unclear. Blood-brain barrier (BBB) dysfunction may be a key factor, particularly in cSVD.

Background: Normothermic ex situ heart perfusion (ESHP) has emerged as a valid modality for advanced cardiac allograft preservation and conditioning prior to transplantation though myocardial function declines gradually during ESHP thus limiting its potential for expanding the donor pool. Recently, the utilization of dialysis has been shown to preserve myocardial and coronary vasomotor function. Herein, we sought to determine the changes in myocardial metabolism that could support this improvement.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

Department of Community Health Sciences, University of Calgary, Calgary, Alberta, CANADA; O'Brien Institute for Public Health, Cumming School of Medicine, University of Calgary, Calgary, Alberta, CANADA.

Rationale & Objective: People with advanced kidney disease undergo more non-cardiac operations compared to the general population, with a higher risk of perioperative cardiac events and death. However, little is known about the associations between severity of preoperative kidney dysfunction with postoperative length of hospitalization and discharge disposition; these were the focus of this study.

Cardiovascular disease (CVD) is a major driver of mortality and declining health worldwide. Cardiovascular diseases (CVD) is the most common cause of morbidity and mortality globally. Although dyslipidemia, smoking, diabetes, hypertension and obesity are some well-known causes of CVD, the overlapping genetic pathways between other diseases and those affecting cardiovascular health have been overlooked.

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).

Long-term Mechanical Circulatory Support in Cardiogenic Shock Secondary to Acromegaly. Case report.

Rev Esp Anestesiol Reanim (Engl Ed)

January 2025

Departamento de ECMO, Fundación Cardiovascular de Colombia, Floridablanca, Colombia. Electronic address:

Heart failure is a complication that may develop in patients diagnosed with acromegaly. This complication can progress to cardiogenic shock, which in cases like the one described, may be refractory to optimal medical management, necessitating the use of mechanical circulatory support as a bridge to decision. Given the specific morphology of this patient's heart, the likelihood of finding a suitable donor in our environment was very low.
