Do you think doctors should routinely monitor heart health in young cancer survivors?
A systematic review and meta-analysis published in Cancers pooled 58 studies from 36 unique cohort sources and found elevated cardiovascular risks among young cancer survivors. Pulmonary embolism, heart failure, venous thrombosis and cardiomyopathy showed the largest pooled hazard ratios.
Why it matters
The findings suggest that cardiovascular monitoring may be important for people who survive cancer at a young age, a group that can face these risks for decades. The evidence is observational, so it highlights associations rather than proven causes.
The pooled analysis of 58 observational studies found pulmonary embolism at a hazard ratio of 4.63 (95% CI 3.03-7.06) and heart failure at 4.08 (95% CI 2.20-7.57). Most outcomes rest on low-certainty evidence, and the cause of the association remains unresolved.
The players
Sylvester Comprehensive Cancer Center
A cancer center at the University of Miami that is one of the largest comprehensive cancer treatment and research institutions in the southeastern United States.
University of Miami
A private research university in Coral Gables, Florida, home to the Miller School of Medicine and the Sylvester Comprehensive Cancer Center.
The details
Researchers pooled relative associations from observational cohort studies of young cancer survivors and compared cardiovascular outcomes against comparison groups. Stroke and arrhythmia showed smaller but still elevated pooled hazard ratios, while cardiovascular mortality estimates varied widely across studies.

Health Landscape
The review builds on long-term cohort work such as the Childhood Cancer Survivor Study, which has documented late cardiovascular effects in people treated for cancer early in life. Pooling 58 studies extends that evidence base, though the underlying data remain observational.
Survivors of cancer diagnosed at a young age may wish to discuss cardiovascular symptoms and screening with their clinicians, particularly for shortness of breath, swelling or palpitations. The findings do not establish that any individual's risk has changed.
The takeaway
Young cancer survivors should consider cardiovascular health part of long-term follow-up care. Discussing symptoms and risk factors with a clinician can help identify problems early.
