Can I get a certificate from the hospital for heart failure that prevents me from going to work and working?

Yes. Heart failure is a syndrome in which the heart's pumping function is impaired for various reasons, and the volume of blood discharged by the heart cannot meet the basic metabolic needs of the whole body. The heart failure requires an electrocardiogram, and an ultrasound of the heart, which can be done in the hospital. Hospitals are healthcare institutions that provide specialized medical staff and medical equipment to patients.
