Cardiovascular disease is the leading cause of excess deaths worldwide. As a result, there has been recent emphasis on the optimization of cardiovascular health (CVH) metrics as a means to reduce the public health burden of atherosclerotic cardiovascular disease and heart failure. Comparably little attention has been paid to cardiac rhythm disorders, which are associated with substantial morbidity and mortality. Studies from the UK Biobank, a prospective cohort of over 500 000 participants, have shown that prevalent arrhythmias are found in∼ 1% of the population under 55 years of age and in∼ 5% of those aged 65 years or older. Atrial fibrillation (AF) is by far the most common arrhythmia and occurs with an incidence rate of 3.1 per 1000 person-years, while supraventricular arrhythmias (1.1 per 1000 person-years) and ventricular arrhythmias (0.5 per 1000 person-years) are relatively less common. 1 There is solid rationale to support the notion that the optimization of CVH metrics may have beneficial effects on arrhythmia risk. The best studied example is AF, where cardiometabolic factors such as hypertension and obesity appear to contribute to atrial fibrosis, left atrial enlargement, and changes to the conduction system that predispose to the initiation and maintenance of arrhythmia. 2 Furthermore, improvement in cardiometabolic parameters appears to have beneficial effects on AF incidence and burden. For example, people with AF who achieve weight loss of> 10% have been shown to have decreases in left atrial volume and AF burden, while physical activity (PA) has been associated with incident AF in an almost dose-dependent manner. 3–5 Consequently, the recently published 2023 ACC/AHA/ACCP/HRS guidelines for the diagnosis and management of AF categorize the optimization of risk factors such as obesity and PA as pillars of AF treatment. 6 But what about other important rhythm disorders such as ventricular arrhythmias or bradyarrhythmias? And rather than investigating individual risk factors, can we gain insight into the effects of CVH holistically using a composite guideline-supported framework, such as the AHA-endorsed CVH metric, sometimes called ‘Life’s Simple 7’? 7 In this issue of the European Journal of Preventive Cardiology, Cheng et al. 8 investigated the association of CVH with incident arrhythmias in the population-based Atherosclerosis Risk in Communities (ARIC) study, a community cohort recruiting over 15 000 people from four communities in the USA between 1987 and 1989. Individuals underwent standardized evaluation of cardiovascular risk factors, and returned for four follow-up visits. Cardiovascular health was defined systematically using Life’s Simple 7, which comprises seven domains of CVH. The seven domains comprise four health behaviours: dietary quality, PA, smoking, and weight, and three health measures: fasting blood glucose, total cholesterol, and blood pressure (BP). As recommended by the AHA, each domain was categorized as poor, intermediate, or ideal using previously defined thresholds. 7 Arrhythmia outcomes were classified into three main groups: AF, ventricular arrhythmias, and bradyarrhythmias, and then ascertained using electrocardiograms performed at study visits, hospitalization records, and death certificates. After excluding individuals with prevalent rhythm disorders, they analysed 13 078 participants for associations between CVH and incident AF, ventricular arrhythmias, and bradyarrhythmias, using separate Cox regression models adjusted for multiple baseline clinical factors. Over a median of 23 years of follow-up, there were a total of 2548 incident AF, 1363 incident …
