Study Slowed heartbeat not responsible for early death

Asymptomatic bradycardia does not increase risk of cardiovascular disease
People with a slow heart rate have an increased risk of heart disease. The presumed physician at least. Now, however, a recent study has shown that sufferers have no increased likelihood of developing heart disease.
When sufferers have asymptomatic bradycardia, they have a very slow heart rate. However, this disease does not mean that people with asymptomatic bradycardia also automatically have to develop heart disease problems. Scientists came to this conclusion in their investigation. The current study published the researchers in the journal "JAMA Internal Medicine".

Slow heartbeat does not increase the risk of developing heart disease
If you have a slow heart rate, you may be suffering from asymptomatic bradycardia. In this condition, the heart beats at a rate of less than 50 beats per minute. In a healthy adult, the heart rate at rest is between 60 and 100 beats per minute, the doctors said. Researchers from the Wake Forest Baptist Medical Center have now come to realize that slow heart rate does not increase the risk of developing heart disease. Thus, sufferers no longer have to worry about the health of their heart, as people with a normal heart rate. The risk of developing cardiovascular disease is not increased for patients with asymptomatic bradycardia, the researchers said.

Study with 6,700 subjects ran over ten years and brought new results
If the heart may not be pumping enough blood through the body, this slow heart rate can cause drowsiness, shortness of breath, fainting or chest pain. "For a vast majority of people with a low heart rate, a slow heart rate does not increase the risk of heart disease," said Drs. Ajay Dharod, one of the authors of the study.

Our findings should be reassuring for those who have been diagnosed with asymptomatic bradycardia, the physician added. The researchers looked at data from more than 6,700 volunteers. They were between the ages of 45 and 84 and lived in the United States. None of the subjects suffered from heart disease when the study began. The health of the subjects was observed by the medical profession more than 10 years ago.

Heart rate modifying drugs are problematic in bradycardia
People with a heart rate less than 50 who otherwise have no signs of heart trouble have no higher risk of developing heart disease than those with a normal heart rate, the researchers said. But people with a low heart rate who use heart rate modifying drugs, such as beta-blockers and calcium antagonists, are at an increased risk of dying from their disease, the researchers said in their recent study. However, the study was not designed to find a cause and effect relationship between these factors. But it could be clearly stated that there is a connection.

Bradycardia can be problematic in people taking medications to slow down heart rate. Dharod. Further research is needed to determine if this association is causally related to heart rate or the use of certain medications. (As)
