A new study on bradycardia has determined that people who have a slower heartbeat do not have increased chances of dying than patients with a normal heart beat. Bradycardia is not linked to early death risk, however, certain heart drugs can increase the risk of death in people suffering from this condition.
Under normal conditions, a healthy adult has a heart rate between 60 and 100 beats per minute. However, there are some instances in which the heart muscle can have either a slower or a faster rhythm. When the heart rate exceeds 100 beats per minute, then the patient has a condition called tachycardia. On the other hand, if the pulse drops below 50 beats per minute, then the condition is called bradycardia.
For some time now, doctors had reasons to believe that people suffering from bradycardia have an increased chance of early death, due to the fact that their heart is beating much too slow. Bradycardia, as any heart condition, may cause any number of complications in some patients. On the other hand, there are many other patients who have this condition but are asymptomatic.
In the case of bradycardia, the heart muscle is incapable of pumping enough blood throughout the body. Patients suffering from this heart conditions may experience symptoms such as syncope (fainting), weakness, chest pains and shortness of breath. Moreover, bradycardia can also account for any number of neurological issues such as confusion or even memory-related issues.
A team of scientists has determined that bradycardia is not linked to early death risk. Due to the fact that there are certain people who do no experience any symptoms, even though their heart is no pumping enough blood, the medical examiners were interested in ascertaining if there is an actual relation between bradycardia and early death risk.
To do so, Doctor Ajay Dharod, the author of the study and his team of medical researchers, consulted the medical records of approximately 6.700 people, with ages ranging from 45 to 85 years old. All of the patients were US citizens and none of them showed any sign of disease before the study began. The doctor and his team followed the health report cards of the patients over the next 10 years.
Dharod discovered that people suffering from bradycardia (had a pulse between 40 and 50 beats per minute), did not have an increased risk of developing a heart disease than patients who had a normal pulse.
Although the study is not focused on the causality on the condition, it has altogether managed to rule out the possibility of early death risk in case of people suffering from bradycardia. However, the doctor and his team did discover that patients taking heart drugs like calcium channel blocker or beta blocker had more chances of dying.
In conclusion, bradycardia is not linked to early death risk for patients who are asymptomatic.
