Coronary artery disease is the leading cause of death for both males and females and accounts for approximately 600,000 deaths in the United States every year. [133] According to present trends in the United States, half of healthy 40-year-old males will develop CAD in the future, and one in three healthy 40-year-old females. [ 134 ]
Distributive shock. Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1][ 2] It is one of four categories of shock, a condition where there is not enough oxygen -carrying blood to meet the metabolic needs ...
Because of poor blood flow to the tissues, patients may have cold extremities. Less blood to the kidneys and brain can cause decreased urine output and altered mental status, respectively. [9] Other signs may be seen depending on the underlying cause. For example, jugular venous distension is a significant finding in evaluating shock.
Clinical death. Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. [1] It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. The term is also sometimes used in resuscitation ...
Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [11] [1] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose consciousness.
Cardiovascular diseases are the leading cause of death worldwide except Africa. [3] Together CVD resulted in 17.9 million deaths (32.1%) in 2015, up from 12.3 million (25.8%) in 1990. [ 5 ] [ 4 ] Deaths, at a given age , from CVD are more common and have been increasing in much of the developing world , while rates have declined in most of the ...
Respiratory failure. Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia.
