Coronary artery disease (CAD) is a medical condition in which the arteries that supply blood to the heart muscle become narrowed or blocked due to the buildup of plaque. It is a common and potentially life-threatening condition that affects millions of people worldwide.

The heart is a vital organ in the human body, responsible for pumping blood throughout the circulatory system. It is located in the chest, between the lungs, and is roughly the size of a fist. The heart is composed of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. Each chamber is separated by a valve, which ensures that blood flows in the correct direction.

Cataracts are a common eye condition that affects millions of people worldwide. They occur when the natural lens in the eye becomes cloudy, causing vision to become blurred, hazy, or distorted.

Myocardial infarction, commonly known as a heart attack, is a serious and potentially life-threatening condition that occurs when the blood supply to a part of the heart muscle is blocked or reduced, leading to damage or death of the affected tissue.

The patient's pulse, according to experienced doctors, is the mirror of heart health. A frequent or low pulse indicates a developing pathology. According to the rhythmic contraction of the heart muscle, doctors judge the blood flow, the health of the bloodstream, the state of the heart as a whole, and if the rhythm deviates from the norm, then this condition is called arrhythmia.

Acne is a disease of the sebaceous glands, another name for this disease is acne. The disease is characterized by blockage and inflammation of the hair follicles.

Amnesia is a pathological condition of a patient in which the cognitive function of memorizing information is impaired, or memory is completely (partially) lost. Sometimes, this pathology occurs in the elderly, and it is associated with natural brain destruction, that is, aging. But in young people, memory loss is associated with other factors.

Amenorrhea is not a disease, but a sign of any physiological, genetic, biochemical, or psycho-emotional illness, and manifests itself as the absence of a menstrual cycle, for six months, in women aged sixteen to forty-five years. There is a false form of this disorder, in which both hormonal and cyclical changes in the uterus and ovaries are preserved, but menstruation itself is absent due to some anatomical obstacle. And with a true form, a woman does not ovulate because of which pregnancy does not occur.
