Most people believe a serious heart condition would come with obvious warning signs. Chest pain, severe discomfort, or a sudden trip to the hospital are often what people expect. But some cardiovascular problems can develop silently for years before they are discovered.
According to researchers from The University of Manchester and Manchester University NHS Foundation Trust, a new study has uncovered evidence that many people in high-risk groups may be living with undiagnosed heart damage, reports Manchester.ac.uk.
Surprising findings
The findings come from the ongoing EARLY-HF study, which is investigating heart failure risk among adults over the age of 50. Participants were required to have at least two common health conditions linked to cardiovascular disease, including high blood pressure, obesity, type 2 diabetes, chronic kidney disease, atrial fibrillation, COPD, or coronary heart disease.
When researchers reviewed the first 550 volunteers, they found that nearly one in ten showed signs of a previous heart attack despite never having received a diagnosis. In addition, almost a quarter of participants were found to have heart or circulatory conditions that required medical attention.

A wider concern
The study also highlighted concerns about blood pressure management. Many participants who had already been diagnosed with high blood pressure were still recording readings above recommended levels.
Key findings included:
- 9% showed evidence of a previously undetected heart attack.
- 23% required medical follow-up for heart or circulatory problems.
- 60% had blood pressure readings above recommended thresholds.
- 30% showed blood markers indicating strain on the heart.
Researchers believe these figures may reflect a broader issue that extends beyond Greater Manchester.
Early detection matters
The EARLY-HF project aims to identify people at risk of heart failure before symptoms become severe. Heart failure affects more than one million people across the UK and can significantly impact quality of life.

The research team says the findings underline the importance of earlier screening, improved prevention strategies, and better engagement with communities that may have limited access to healthcare. The study is continuing to recruit participants while researchers work to improve methods for detecting hidden cardiovascular disease before it progresses.
