Heart failure is a condition where the heart is unable to pump blood effectively, leading to inadequate blood flow to meet the body’s needs. It can be classified into acute and congestive heart failure:
Acute Heart Failure: Sudden onset of symptoms, requiring immediate medical attention. It can be caused by a heart attack, severe infection, or other acute conditions.
Congestive Heart Failure (CHF): A chronic condition characterized by fluid buildup in the lungs and other tissues, causing symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles.
