Study: No Risk of Cardiovascular Disease to People with Slow Heart Rate

Relax! All those people who have some symptoms associated with slow heart rate should not worry anymore as there is no danger to their health. A new study has found that slow heart rate does not increase the risk of heart disease. Bradycardia, a condition associated with slow heart beat, generally occurs when a heart beat becomes fewer than 50 beats per minute, between 10 and 50 fewer beats than normal for an adult. For a normal person, the heart beat varies 60 to 100 beats-per-minutes an adult heart is expected to maintain at rest.

Bradycardia is generally associated with light-headedness, shortness of breath, fainting or chest pain. But, researchers have finally found that people with slow heart beat are not at an increased risk of developing cardiovascular disease. Bradycardia may be problematic in people who are taking medications that also slow their heart rate. Dr. Ajay Dharod, a professor of internal medicine at Wake Forest Baptist Hospital, the prognosis is very good for a large majority of people with a heart rate in the 40s or 50s who have no symptoms. He said the findings could act as a breath of relief for those diagnosed with asymptomatic bradycardia.

Researchers analyzed data on 6,733 people collected as part of the Multi-Ethnic Study of Atherosclerosis from 2000 to 2002, during the 10-year study. Researchers reported people with an average heart rate lower than 50 beats per minute were not associated with cardiovascular disease, and the mortality risk among people not taking heart rate modifying drugs was about the same for people whose heart rates were either below 50 or above 80. Among the 902 participants taking heart rate modifying drugs, the risk for cardiovascular disease was no higher than those not on the drugs. The findings of the study has been published in JAMA Internal Medicine.
