CCF is associated with Increase in all of the following except –
**Core Concept**
Congestive Cardiac Failure (CCF) is a condition where the heart fails to pump enough blood to meet the body's needs, leading to fluid buildup in various organs. The pathophysiology of CCF involves increased afterload, preload, and contractility, which can be due to various factors such as hypertension, coronary artery disease, or valvular heart disease.
**Why the Correct Answer is Right**
CCF is characterized by an increase in systemic vascular resistance (SVR), which is a measure of the resistance to blood flow in the systemic circulation. This increase in SVR is a compensatory mechanism to maintain blood pressure in the face of decreased cardiac output. Additionally, CCF is associated with an increase in pulmonary vascular resistance (PVR), which can lead to pulmonary congestion and edema.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not correct because CCF is not associated with an increase in cardiac output. In fact, cardiac output is typically decreased in CCF.
* **Option B:** Incorrect because CCF is associated with an increase in pulmonary capillary wedge pressure (PCWP), which is a measure of left atrial pressure and is used to assess left ventricular function.
* **Option C:** This option is not correct because CCF is associated with an increase in systemic capillary pressure, which can lead to peripheral edema and fluid buildup in the lungs.
**Clinical Pearl / High-Yield Fact**
CCF can be classified into four stages based on the New York Heart Association (NYHA) functional classification system: Class I (no symptoms), Class II (mild symptoms), Class III (moderate symptoms), and Class IV (severe symptoms).
**Correct Answer: A. Cardiac output**
