Identifying Heart Failure Risk in Diabetic Patients

Core Concepts
Two-step screening using risk scores and biomarkers can effectively identify diabetic patients at high risk for heart failure.
TOPLINE: Two-step screening with risk score and biomarkers can identify high-risk diabetic patients for heart failure prevention. METHODOLOGY: Study compared screening methods for heart failure risk in diabetic patients without ASCVD. Data from 4889 diabetic patients aged ≥40, no heart failure, and no ASCVD. One-step screening with clinical risk score, biomarker tests, or echocardiography. Two-step strategy for high-risk individuals using a combination of tests. Primary outcome: incident heart failure in 5 years. TAKEAWAY: 6.2% heart failure events in participants without ASCVD. 3.0- to 3.6-fold higher risk for heart failure in high-risk group identified by two-step screening. WATCH-DM score followed by selective NT-proBNP testing was the most efficient strategy. IN PRACTICE: Matching preventive therapies to high-risk individuals can be cost-effective for heart failure prevention. SOURCE: Study led by Kershaw Patel published in Circulation. LIMITATIONS: Study may not be generalized due to older adults with comorbidities. Some diabetic individuals may have been missed due to screening limitations. DISCLOSURES: Authors had financial relationships with pharmaceutical companies.
Overall, 301 (6.2%) heart failure events occurred among participants without ASCVD. The risk for incident heart failure was 3.0- to 3.6-fold higher in the high- vs low-risk group identified using a two-step screening approach. The study included data from 4889 patients with diabetes.
"Matching effective but expensive preventive therapies to the highest-risk individuals who are most likely to benefit would be an efficient and cost-effective strategy for heart failure prevention." - Authors

Deeper Inquiries

How can the findings of this study be applied to other populations or age groups?

The findings of this study can be extrapolated to other populations or age groups by considering the underlying mechanisms of heart failure in individuals with diabetes. While the study focused on older adults with a high burden of comorbidities, the principles of using a two-step screening approach involving risk scores and biomarkers can be adapted to different age groups. By understanding the importance of early detection and preventive measures in high-risk individuals, healthcare providers can tailor screening strategies to suit the specific characteristics and risk factors prevalent in other populations.

What are the potential drawbacks of relying solely on risk scores and biomarkers for heart failure risk assessment?

Relying solely on risk scores and biomarkers for heart failure risk assessment may have limitations. Risk scores and biomarkers provide valuable insights into an individual's likelihood of developing heart failure, but they may not capture all relevant factors contributing to heart failure risk. Factors such as diabetes duration, socioeconomic status, lifestyle habits, and genetic predispositions can influence heart failure risk but may not be fully accounted for in traditional risk assessment tools. Additionally, biomarkers can be influenced by various non-cardiac conditions, leading to potential false positives or negatives. Therefore, a comprehensive approach that integrates multiple risk factors and clinical parameters is essential for a more accurate assessment of heart failure risk.

How can socioeconomic factors be integrated into heart failure risk screening strategies?

Socioeconomic factors play a crucial role in determining an individual's risk of heart failure. Integrating socioeconomic factors into heart failure risk screening strategies involves considering variables such as income level, education, access to healthcare, and living conditions. Healthcare providers can incorporate socioeconomic data into risk assessment tools to identify individuals at higher risk due to social determinants of health. Additionally, targeted interventions, such as patient education programs, community outreach initiatives, and access to affordable healthcare services, can help address disparities in heart failure risk among different socioeconomic groups. By recognizing and addressing socioeconomic factors, healthcare professionals can enhance the effectiveness of heart failure prevention strategies and improve outcomes for at-risk populations.
