Holy month Ramadan is auspicious for worldwide Muslims and most of them starts fasting early in the morning up to the sunset in the evening during this entire month.

 Heart disease patients tend to fast during Ramadan but they have many questions:

Many studies comparing Ramadan with other months in cardiac patients shows there is no significant differences in the incidence of heart attack or typical cardiac chest pain during Ramadan. Patients with recent acute heart attack, heart attack equivalent chest pain with high cardiac enzymes, recent stenting, recent open heart surgery should strictly avoid fasting.

B.      Patients with low pumping of heart

Low pumping of the heart is one of the common cause of frequent hospitalisations among cardiac patients. Many studies done in the middle east shows there was no significant difference in the number of hospitalizations for patients with low heart pumping during Ramadan. Its almost similar to other months without fasting. But in this category certain groups of patients cannot fast especially patients with difficulty in breathing, associated swelling of legs, associated cough and sudden increase in weight.
