Systemic congestion

Introduction Right heart failure causes systemic congestion and increased venous pressure. It can cause venous congestion of the corresponding organ or tissue. However, due to the large number of branches of the vein, only when the venous cavity is blocked and the blood flow cannot be fully passed through the lateral branch, the venous congestion of the venous circulation is an important cause of the metabolic changes of many organs. If mitral valvular disease and essential hypertension cause left ventricular dysfunction, tissues and organs that can cause venous congestion of the pulmonary congestion may be swollen due to blood deposition; venous congestion occurs on the surface of the body due to blood Reduced oxyhemoglobin, increased hemoglobin, local purpura; venous congestion, microscopic venules and telangiectasia, full of blood, sometimes accompanied by edema. Pulmonary heart disease leading to right heart dysfunction can cause liver, kidney and lower limbs and other organs to cause congestion, causing systemic congestion.

Cause

When mitral valvular disease and essential hypertension cause left ventricular dysfunction, tissues and organs that can cause venous congestion of the pulmonary congestion may be swollen due to blood deposition; venous congestion occurs on the surface of the body due to blood Oxygenated hemoglobin is reduced, reduced hemoglobin is increased, localized may be purpura; and due to local blood flow stasis, capillary expansion, resulting in increased heat dissipation, the temperature of the body surface is thus reduced. Venous congestive tissue, microscopically venous and telangiectasia, full of blood, sometimes accompanied by edema. As local blood oxygen partial pressure decreases, organs and tissues are relatively hypoxic, and metabolic functions can be attenuated. Pulmonary heart disease leading to right heart dysfunction can cause liver, kidney and lower limbs and other organs to cause congestion, causing systemic congestion.

Right heart failure is mainly characterized by systemic congestion.

(1) Gastrointestinal symptoms: long-term gastrointestinal congestion, can cause loss of appetite, abdominal distension, nausea, vomiting, constipation and upper abdominal pain.

(2) Kidney symptoms: Kidney congestion causes renal dysfunction, less urine during the day, and nocturia. There may be a small amount of proteinuria, a few transparent or granular casts and red blood cells. Blood urea nitrogen can be elevated.

(3) Pain in the liver area: Hepatic congestion and hematoma, the liver capsule is dilated, the upper right abdomen is full of discomfort, and the liver area is painful. In severe cases, severe pain can occur and it is misdiagnosed as acute abdomen and other diseases.

(4) Dyspnea: In the case of simple right heart failure, there is usually no pulmonary congestion, and there is no obvious left heart failure in asthma.

Differential diagnosis

Systemic congestion is right heart failure. Attention should be paid to the identification of three types of heart failure: heart failure is caused by chronic heart disease and long-term ventricular overload, resulting in impaired myocardial contractility, difficulty in blood discharge, venous system bleeding, and decreased arterial volume. A heart disease that does not meet the metabolic needs of the tissue.

The disease is divided into three types: left heart failure, right heart failure and heart failure. Most right heart failure is caused by left heart failure affecting the right heart. The main clinical symptoms are heart and chest cramps, tightness and discomfort, or heart and chest suffocation such as physical pressure, or chest tightness, shortness of breath, palpitations, tongue hemiplegia, pulse string slip.
