A new study from the European Sudden Cardiac Arrest Network has found a possible link between a common blood pressure medication and a higher risk of sudden cardiac arrest (SCA).
This discovery could be important for both doctors and patients who use these drugs to protect their heart health.
Sudden cardiac arrest happens when the heart suddenly stops beating. When this occurs, blood stops flowing to the brain and other organs. If help doesn’t come quickly, it can lead to death within minutes.
In Europe, SCA causes about half of all deaths related to heart problems and accounts for one in five natural deaths. People who suffer from SCA often lose consciousness and may stop breathing normally.
In this study, scientists looked at two popular drugs used to treat high blood pressure and chest pain—nifedipine and amlodipine. They reviewed health records from thousands of patients to see if there was any connection between these drugs and sudden cardiac arrest.
The results were surprising. The study found that people who took high doses of nifedipine were more likely to suffer from SCA. However, people taking amlodipine did not face the same risk. This finding was unexpected because both drugs have been used for many years without showing signs of this kind of danger.
Researching SCA is difficult because it happens so fast. This might be why the link between high-dose nifedipine and SCA had not been seen before.
The researchers suggest that patients who take nifedipine—especially in high doses—should be careful. They should pay attention to warning signs like chest pain, shortness of breath, or feeling sick. These symptoms could be early signs of trouble and should be taken seriously.
Doctors are also encouraged to be cautious when giving high doses of nifedipine to patients with heart problems. They may want to consider other treatment options or lower the dose.
The scientists who conducted the study say more research is needed to be sure about this possible risk. So far, the findings do not mean people should stop taking nifedipine. Instead, the study is a reminder to stay alert and to talk to a healthcare provider if there are any concerns.
This research shows the importance of ongoing studies about SCA and how medications affect heart health. It also highlights the need for safer treatment plans and better ways to manage high blood pressure.
In short, nifedipine is still an effective drug for treating high blood pressure and chest pain, but it may carry risks—especially at high doses. Patients and doctors should work together to make careful, informed decisions to protect heart health.
