Detailed explanation-1: -Left ventricular failure may cause blood to back up into the lungs and cause pulmonary edema. This edema can lead to pulmonary hypertension and excessive strain to the right atrium and ventricle.
Detailed explanation-2: -Left ventricular hypertrophy changes the structure and function of the heart. The thickened left ventricle becomes weak and stiff. This prevents the lower left heart chamber from filling properly with blood. As a result, blood pressure in the heart increases.
Detailed explanation-3: -Left-sided heart failure: The left ventricle of the heart no longer pumps enough blood around the body. As a result, blood builds up in the pulmonary veins (the blood vessels that carry blood away from the lungs). This causes shortness of breath, trouble breathing or coughing – especially during physical activity.
