Comprehensive multiple risk factor control in cancer survivors to mitigate heart failure risk: insights from a...

Area of Science:

• Cardiovascular Medicine
• Oncology
• Public Health

Background:

• Cancer survivors face an elevated risk of heart failure (HF) compared to the general population.
• Understanding modifiable risk factors is crucial for preventing HF in this vulnerable group.

Purpose of the Study:

• To assess the association between comprehensive cardiovascular risk factor control and the incidence of heart failure (HF) among cancer survivors.
• To determine the impact of managing multiple risk factors on HF risk in cancer survivors.

Main Methods:

• Utilized UK Biobank data, including 14,466 cancer survivors and 57,864 matched controls.
• Assessed joint risk factor control (blood pressure, BMI, LDL-C, HbA1c, renal function, smoking, physical activity, diet).
• Employed Cox proportional hazards models to analyze the association between risk factor control and HF risk over a median follow-up of 12.54 years.

Main Results:

• Each additional controlled risk factor was linked to a 12% reduction in HF risk (HR: 0.88).
• Controlling at least five risk factors was associated with a 24% lower HF risk (HR: 0.76) in cancer survivors.
• Achieving comprehensive risk factor control in survivors resulted in HF risk comparable to that of individuals without a cancer history.

Conclusions:

• A dose-response relationship exists between the level of joint risk factor control and reduced HF risk in cancer survivors.
• Intensive management of modifiable cardiovascular risk factors is a key strategy for mitigating HF post-cancer treatment.
• Promoting healthy lifestyle choices and medical management can significantly improve cardiovascular outcomes for cancer survivors.
