Key Takeaway
Note that patients with cardiovascular diseases have a measurable prevalence of active cancer across various conditions.

This systematic review and meta-analysis evaluates the prevalence of various types of cancer, including blood, solid, and metastatic cancers, in patients with cardiovascular diseases and associated risk factors. The analysis included a large sample size of 4,759,695 for active cancer analysis.

The synthesis identifies specific active cancer prevalence rates across several conditions: 4.43% in Type 2 DM (95% CI 2.78-6.38), 4.90% in chronic HF (95% CI 3.84-6.37), and 4.61% in CAD (95% CI 2.83-6.97). Other conditions showed prevalence rates of 5.55% for VHD (95% CI 3.97-7.01) and 4.22% for AF (95% CI 2.18-5.32). The study also reported higher figures for any cancer prevalence, such as 14.10% in AF (95% CI 12.20-15.99) and 7.04% in CAD (95% CI 6.05-8.03).

The authors note that these figures represent prevalence rather than causal links between cardiovascular disease and cancer. The findings highlight the need for multidisciplinary management of patients with cardiovascular diseases due to the measurable cancer burden identified in this population.

How this fits prior evidence

This meta-analysis addresses a gap by quantifying the concurrent cancer burden in patients with conditions like atrial fibrillation (AF) and coronary artery disease (CAD). While prior evidence has explored specific biomarkers for atrial fibrillation and genetic polymorphisms associated with coronary artery disease, this study provides data on the prevalence of active cancer within these same patient populations.

Living with a heart condition is already a heavy burden, but new data suggests there may be another layer of risk to consider. A large study looked at nearly 4.8 million people with various cardiovascular issues, including high blood pressure and heart failure, to see how often they also faced cancer diagnoses.

The findings show that active cancer was present in about 4.6% of patients with coronary artery disease and 4.9% of those with chronic heart failure. For those who had suffered a stroke, the rate was 4.6%. The study also noted higher rates for specific conditions: 5.55% for valvular heart diseases and 4.22% for atrial fibrillation.

It is important to remember that this data shows how often these two conditions appear together in patients, not that one causes the other. Because of these overlapping risks, experts suggest that doctors who treat heart disease should work closely with cancer specialists to provide the best care possible.

What this means for you:
Patients with heart conditions like stroke or heart failure show measurable rates of active cancer cases.

Common questions

Does having a heart condition cause cancer?

The study does not show that heart disease causes cancer. It only shows how often both conditions appear together in patients. Because these two issues can happen at once, doctors recommend a team of specialists to manage both conditions.

What are the cancer rates for other heart conditions?

The study found active cancer rates of 4.61% for coronary artery disease and 5.55% for valvular heart diseases. For those with atrial fibrillation, the rate was 4.22%.

Background No systematic review has been conducted to pool the existing evidence and quantify cancer prevalence rates in cardiovascular diseases (CVDs). We aimed to estimate pooled cancer prevalence in coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), hypertension, type 2 diabetes mellitus (DM), stroke, peripheral arterial disease (PAD), and valvular heart diseases (VHD). Methods PubMed, Web of Science, and Scopus were searched from 2010 to July 2024. The outcomes were proportions of patients with active, any, previous, blood, solid, and metastatic cancer. The prevalence rates were estimated via one-step generalized linear mixed models. Results Totally, we retrieved 676 studies with enrollment of roughly 180 million participants. The analysis for active cancer included 59 studies with a population of 4,759,695 patients. The pooled prevalence of active cancer was 4.22% (95% confidence interval (CI) 2.18-5.32), 4.43% (95% CI 2.78-6.38), 4.60% (95% CI 1.72-8.13), 4.61% (95% CI, 2.83-6.97), 4.90% (95% CI 3.84-6.37), and 5.55% (95% CI 3.97-7.01) in patients with type 2 DM, chronic HF, any stroke, CAD, VHD, and AF. For any cancer, prevalence rates ranged from 14.10% (95% CI 12.20-15.99) in AF to 7.04% (95% CI 6.05-8.03) in CAD. Conclusion Pooled prevalence rates demonstrate a measurable burden of cancer among patients with a wide range of CVDs, highlighting the need for multidisciplinary management in this population.
