COPD (Chronic Obstructive Pulmonary Disease) is a lung disease that makes it difficult to breathe. It is primarily caused by smoking and long-term exposure to other irritants such as air pollution, chemical fumes, or dust.
While COPD affects the lungs, it can also have effects on the heart, as the lungs and heart are closely connected. COPD can cause low oxygen levels in the blood, which can put additional strain on the heart and lead to conditions such as pulmonary hypertension (high blood pressure in the arteries of the lungs) and right-sided heart failure. Therefore, while COPD is primarily a lung disease, it can have secondary effects on the heart.
