Cardiovascular disease prevention: Risk factor modification at the heart of the matter

Feasibility of alcohol interventions in cardiology: A qualitative study of clinician perspectives in Sweden

AIM

To identify barriers and facilitators to implementing alcohol screening and brief interventions (SBI) in cardiology services.

METHODS AND RESULTS

Qualitative study. Individual, semi-structured interviews were conducted with 24 clinical cardiology staff (doctors, nurses, assistant nurses) of varying experience levels, and from various clinical settings (high dependency unit, ward, outpatient clinic), in three regions of Sweden. Reflexive thematic analysis was used, with deductive coding applying the Capability, Opportunity, Motivation (COM-B) theoretical framework. A total of 41 barriers and facilitators were identified, including twelve related to capability, nine to opportunity, and 20 to motivation. Four themes were developed: 1. Uncharted territory, where clinicians expressed a need to address alcohol use but lacked knowledge and a roadmap for implementing SBI; 2. Cardiology as a cardiovascular specialty, where tasks were prioritized according to established roles; 3. Alcohol stigma, where alcohol was reported to be a sensitive topic that staff avoid discussing with patients; 4. Window of opportunity, where staff expressed potential for implementing SBI in routine cardiology care.

CONCLUSION

Findings suggest that opportunities exist for early identification and follow-up of hazardous alcohol use within routine cardiology care. Several barriers, including low knowledge, stigma, a lack of ownership, and a greater focus on other risk factors must be addressed prior to the implementation of SBI in cardiology. To meet current clinical guidelines, there is a need to increase awareness and to improve pathways to addiction care. In addition, there may be a need for clinicians dedicated to alcohol interventions within cardiology services.

The Heart–Brain Interplay in Multiple Sclerosis from Pathophysiology to Clinical Practice: A Narrative Review

Multiple sclerosis (MS) is a chronic neurological disorder characterized by inflammation in the central nervous system (CNS) that leads to neurodegeneration. The clinical course is highly variable, but its prevalence is rising worldwide, partly thanks to novel disease-modifying therapies. Additionally, the lifespan of people with MS is increasing, and for this reason, it is fundamental to have a multidisciplinary approach to MS. MS may be associated with cardiovascular diseases (CVD), but there is scarce attention on this issue. In particular, CNS is essential in regulating the autonomic system and heart activity. Moreover, cardiovascular risk factors show a higher prevalence in MS patients. On the other hand, conditions like Takotsubo syndrome are rare complications of MS. The parallelism between MS and myocarditis is also interesting. Finally, cardiac toxicity represents a not infrequent adverse reaction to MS drugs. This narrative review aims to provide an overview of cardiovascular complications in MS and their management to prompt further clinical and pre-clinical research on this topic.

Associations of risk factor burden and genetic predisposition with the 10-year risk of atrial fibrillation: observations from a large prospective study of 348,904 participants

BACKGROUND

Understanding the effects of risk factor burden and genetic predisposition on the long-term risk of atrial fibrillation (AF) is important to improve public health initiatives. However, the 10-year risk of AF considering risk factor burden and genetic predisposition is unknown.

METHODS

A total of 348,904 genetically unrelated participants without AF at baseline from the UK were categorized into three groups: index ages 45 years (n = 84,206), 55 years (n=117,520), and 65 years (n=147,178). Optimal, borderline, or elevated risk factor burden was determined by body mass index, blood pressure, diabetes mellitus, alcohol consumption, smoking status, and history of myocardial infarction or heart failure. Genetic predisposition was estimated using the polygenic risk score (PRS), constructed using 165 predefined genetic risk variants. The combined effects of risk factor burden and PRS on the risk of incident AF in 10 years were estimated for each index age. Fine and Gray models were developed to predict the 10-year risk of AF.

RESULTS

The overall 10-year risk of AF was 0.67% (95% CI: 0.61-0.73%) for index age 45 years, 2.05% (95% CI: 1.96-2.13%) for index age 55 years, and 6.34% (95% CI: 6.21-6.46%) for index age 65 years, respectively. An optimal risk factor burden was associated with later AF onset regardless of genetic predisposition and sex (P < 0.001). Significant synergistic interactions were observed for risk factor burden with PRS at each index age (P < 0.05). Participants with an elevated risk factor burden and high PRS had the highest 10-year risk of AF in reference to those who had both an optimal risk factor burden and a low PRS. At younger ages, optimal risk burden and high PRS might also lead to later onset of AF, compared to the joint effect of elevated risk burden and low/intermediate PRS.

CONCLUSIONS

Risk factor burden together with a genetic predisposition is associated with the 10-year risk of AF. Our results may be helpful in selecting high-risk individuals for primary prevention of AF and facilitating subsequent health interventions.
