Atrial Fibrillation Can Be Calmed by Ablation
Atrial fibrillation is the most common heart beat irregularity that is usually found in people. And thus the researchers from Emory University School of Medicine made a study and found that the risk of this heart beat irregularity can be predicted by measuring oxidative stress levels. Researchers also found a new link between oxidative stress and enlargement of the heart's left atrium, which is the main cause of occurrence of atrial fibrillation.
Atrial fibrillation highly increases the risk of a stroke in a patient as it causes unproductive pumping and pooling of blood, which may sometimes occur blood clots in the heart's upper chambers (the atria).
Emory cardiology researcher Nima Ghasemzadeh along with Arshed Quyyumi, Professor of Medicine and Director of the Emory Cardiovascular Research Institute, studied 629 patients, averagely under the age group of 63, undergoing cardiac catheterization at Emory for three years and found that the risk of atrial fibrillation increases with age, and approx 3%-5% people over 65 suffer from atrial fibrillation.
Some of the other counted risk factors of atrial fibrillation are high blood pressure, obesity, diabetes, smoking and previous heart disease.
Researchers also marked some of the symptoms of atrial fibrillation such as rapid heart rate, palpitations and shortness of breath but they also said that these symptoms can be periodic and can vary in severity of the occurrence of same.
