No, congestive heart failure (CHF) is not part of heart attack type 2. Heart attack type 2 is a specific type of heart attack that occurs when the heart muscle doesn't get enough oxygen because of a mismatch between supply and demand, often in a stressful situation. CHF, on the other hand, is a condition where the heart can't pump enough blood to meet the body's needs, leading to fluid buildup and congestion. While a heart attack can sometimes lead to CHF, they are distinct conditions.
