Many women have undiagnosed heart failure, study finds

Heart failure is a condition that affects millions of people worldwide. Early diagnosis and treatment can significantly improve patients’ quality of life and increase their chances of survival.

However, a recent study presented at Heart Failure 2023, a scientific congress of the European Society of Cardiology (ESC), has revealed a troubling trend: many cases of heart failure go undiagnosed until it’s too late.

The Hidden Danger of Undiagnosed Heart Failure

Heart failure is a progressive condition where the heart struggles to pump blood effectively, leading to a range of symptoms like breathlessness and ankle swelling.

While effective treatments are available, they can only help if the condition is identified early. Unfortunately, the study’s findings suggest that a significant number of patients with heart failure are not getting the diagnosis they need.

Patients with heart failure often experience symptoms and signs for an extended period before receiving a diagnosis. In many cases, diagnosis only occurs after severe symptoms force a hospital visit.

To manage these symptoms, doctors often prescribe loop diuretics, which help remove excess fluid from the body.

The study conducted by the University of Glasgow, UK, examined electronic health records for around one million adults in the Greater Glasgow and Clyde area of Scotland.

The goal was to understand the relationship between a diagnosis of heart failure, the use of loop diuretics, and patient outcomes.

Startling Findings

The study uncovered some startling findings:

  • Of the patients receiving loop diuretics, only 25% had been diagnosed with heart failure.
  • A significant proportion of patients taking loop diuretics without a heart failure diagnosis were women.
  • Over the next five years, three times more patients started taking loop diuretics than were diagnosed with heart failure.
  • Few patients initiated on loop diuretics were investigated for heart failure, even though they had blood tests that could have helped diagnose the condition.

A Missed Opportunity for Treatment

Perhaps the most concerning discovery was that many patients who started taking loop diuretics without a heart failure diagnosis eventually passed away without ever receiving the needed diagnosis.

This suggests a missed opportunity for early treatment that could have improved their outcomes.

Professor John Cleland, the principal investigator of the study, highlights the urgent need for action. He emphasizes that any patient prescribed loop diuretics should be thoroughly investigated for underlying heart disease.

This investigation could involve measuring natriuretic peptides or conducting an echocardiogram.


Undiagnosed heart failure represents a significant challenge in cardiovascular medicine. The study’s findings underscore the importance of early diagnosis and appropriate treatment.

Ignoring this issue could have dire consequences for patients, making it crucial for healthcare providers to be vigilant in identifying and managing heart failure promptly.
