Article Synopsis
- Smoking significantly increases the risk of sudden cardiac death (SCD) in patients with acute coronary syndrome (ACS), with active smokers showing a 79% higher risk compared to nonsmokers.
- A study involving nearly 10,000 ACS patients found that 23.7% were active smokers and 20.8% were ex-smokers, with active smokers being notably younger than their nonsmoking counterparts.
- The findings emphasize the importance of promoting smoking cessation after an ACS event and suggest that smoking status should be factored into future research on SCD risks.
Background: Computer-interpreted electrocardiogram (CIE) data is provided by almost all commercial software used to capture and store digital electrocardiograms. CIE is widely available, inexpensive, and accurate. We tested the potential of CIE in long-term sudden cardiac death (SCD) risk prediction.

The pre-interventional assessment in patients undergoing invasive treatment for peripheral arterial disease is increasingly often carried out with magnetic resonance imaging (MRI), and we therefore sought to investigate the predictive potential of MRI-derived psoas muscle area in this cohort.
Methods: A total of 899 patients with available sufficient quality pre-interventional MRI conducted within 6 months prior to treatment undergoing open, endovascular, or hybrid revascularization procedures for claudication and/or limb-threatening ischemia at Tampere University hospital between 2010 and 2020 were retrospectively studied in this single-center cohort study.
Diabetes and mortality risk in patients undergoing coronary angiography: The KARDIO study.
Catheter Cardiovasc Interv
October 2024
Background: Diabetes is an established risk factor for adverse cardiovascular outcomes including mortality, but the relationship between diabetes and mortality risk in the presence of the extensive or diffuse form of coronary artery disease (CAD) is controversial.
Aims: We evaluated the association between diabetes and mortality risk in patients who underwent coronary angiography using a real-life clinical database.
Methods: We utilized the KARDIO registry, which comprised data on demographics, prevalent diseases, including diabetes status, cardiovascular risk factors, coronary angiographies, and other interventions in 79,738 patients.
Prediction of Sudden Cardiac Death With Ultra-Short-Term Heart Rate Fluctuations.
JACC Clin Electrophysiol
September 2024
Background: Conventional measures of heart rate variability (HRV) have shown only modest associations with sudden cardiac death (SCD). Detrended fluctuation analysis (DFA), with novel methodological developments to evaluate the short-term scaling exponent, is a potentially superior method compared to conventional HRV tools.
Objectives: In this study, the authors studied the analysis of the association between DFA and SCD.
