The results of tests with physical load on a bicycle ergometer and treadmill in 50 patients with ischemic heart disease were compared. The control group was formed of 20 patients with neurocirculatory dystonia. Agreement between the results of both tests was encountered in 90% of patients with ischemic heart disease. The authors conclude that the tests do not differ essentially in the main indices (rate of cardiac contractions, index of cardiac activity at the peak of the load, time of uninterrupted work until the criteria of load cessation). It is suggested that tests on the treadmill and those on the bicycle ergometer in patients with ischemic heart disease are equivalent.

Association between early age body mass index and the risk of adulthood cardiovascular diseases: a systematic review and meta-analysis.
Int J Obes (Lond)
January 2025
Department of Cardiology, Peking University First Hospital, Beijing, China.
Background: Several studies have attempted to demonstrate the associations between body mass index (BMI) in early age and cardiovascular diseases (CVDs). However, their findings were inconsistent and inconclusive, indicating the need for further investigation.
Methods: We conducted a systematic review and meta-analysis of studies focusing on BMI in early age (age from 2 to 22) in relation to CVDs in adulthood, including coronary artery disease (CHD), ischemic and hemorrhagic stroke, myocardial infarction and heart failure.
The highly conserved PIWI-interacting RNA CRAPIR antagonizes PA2G4-mediated NF110-NF45 disassembly to promote heart regeneration in mice.

Targeting the cardiomyocyte cell cycle is a promising strategy for heart repair following injury. Here, we identify a cardiac-regeneration-associated PIWI-interacting RNA (CRAPIR) as a regulator of cardiomyocyte proliferation. Genetic ablation or antagomir-mediated knockdown of CRAPIR in mice impairs cardiomyocyte proliferation and reduces heart regenerative potential.

Objectives: Physical activity (PA) provides protective effects against cardiovascular diseases, including ischaemic heart disease. However, recommending moderate to vigorous PA (MVPA) to patients with recent acute coronary syndrome (ACS) raises concerns owing to potential risk of recurrent ACS or fatal arrhythmias. This study investigated the association between longitudinal PA changes following an ACS diagnosis and subsequent cardiovascular outcomes, including non-fatal coronary events, non-fatal stroke and cardiovascular mortality.

Background: The risk-benefit ratio of the Absorb bioresorbable vascular scaffold (BVS) may vary before and after 3 years, the time point of complete bioresorption of the poly-L-lactic acid scaffold.
Objectives: The aim of this study was to determine the time-varying outcomes of the Absorb BVS compared with cobalt-chromium everolimus-eluting stents (EES) from a large individual-patient-data pooled analysis of randomized trials.
Methods: The individual patient data from 5 trials that randomized 5,988 patients undergoing percutaneous coronary intervention to the Absorb BVS vs EES with 5-year follow-up were pooled.
Ex-vivo lung perfusion: National trends and post-transplant outcomes.

Department of Cardiothoracic Surgery, Vanderbilt University Medical Center, Nashville, Tennessee.
Background: Ex-vivo lung perfusion (EVLP) has potential to expand donor lung utilization, evaluate allograft viability, and mitigate ischemia-reperfusion injury. However, trends in EVLP use and recipient outcomes are unknown on a national scale. We examined trends in EVLP use and recipient outcomes in the United States.
