Over time, fat and cholesterol, as well as inflammatory cells and cellular waste products, can build up along the arteries' walls, forming a plaque of hardened material. Your coronary arteries are hollow tubes that carry oxygenated blood away from the heart and to the rest of the body. What is coronary artery disease?Ĭoronary artery disease (CAD) is the most common form of heart disease. They try to find practical solutions, including lifestyle changes, to minimize their patients’ risks of developing heart disease and they work hard to manage the condition if and when it’s diagnosed. Priya Gandhi take your heart health very seriously. adults, or 48%, have some form of cardiovascular disease, while the CDC found that nearly 634,000 people died from it in 2015, making it the leading killer of Americans.Īt Medinet Family Care Clinic in Houston and Sugar Land, Texas, Dr. These symptoms can signal a heart attack.Ī 2019 report in the journal Circulation indicated that 121.5 million U.S. Heart disease is also a term often used synonymously with cardiovascular disease, though the two reflect different conditions.Ĭardiovascular disease generally involves the narrowing or blockage of blood vessels, which can present with symptoms ranging from “typical” chest pain to shortness of breath and even to back pain, especially in women.
Researchers suggest that the activity (expression) of the SGO1 gene in certain embryonic tissues or a particular function of the SGO1 protein in the SA node and in cells that help control peristalsis may account for the features of the disorder.Heart disease is an umbrella term for a number of conditions that affect the heart. It is unclear why SGO1 gene mutations specifically affect the heart and intestines in CAID. This instability is thought to cause early aging (senescence) of cells in the intestinal muscle and in the SA node, resulting in problems maintaining proper rhythmic movements of the heart and intestines and leading to the signs and symptoms of CAID. Researchers suggest that SGO1 gene mutations may result in a cohesin complex that is less able to hold sister chromatids together, resulting in decreased chromosomal stability during cell division. Cohesin holds the sister chromatids together, and in doing so helps maintain the stability of chromosomal structure during cell division. The copied DNA from each chromosome is arranged into two identical structures, called sister chromatids, which are attached to one another during the early stages of cell division. Before cells divide, they must copy all of their chromosomes. This protein complex helps control the placement of chromosomes during cell division. This gene provides instructions for making part of a protein complex called cohesin. These symptoms resemble those caused by an intestinal blockage (obstruction) such as a tumor, but in intestinal pseudo-obstruction no such blockage is found.ĬAID is caused by mutations in the SGO1 gene. Affected individuals experience loss of appetite and impaired ability to absorb nutrients, which may lead to malnutrition. In intestinal pseudo-obstruction, impairment of peristalsis leads to a buildup of partially digested food in the intestines, abdominal swelling (distention) and pain, nausea, vomiting, and constipation or diarrhea. During exercise, many affected individuals experience chest pain, difficulty breathing, or excessive tiredness (fatigue). Symptoms related to abnormal heartbeats can include dizziness, light-headedness, fainting (syncope), a sensation of fluttering or pounding in the chest (palpitations), and confusion or memory problems. In people with sick sinus syndrome, the SA node does not function normally, which usually causes the heartbeat to be too slow (bradycardia), although occasionally the heartbeat is too fast (tachycardia) or rapidly switches from being too fast to being too slow (tachycardia-bradycardia syndrome). These signals travel from the SA node to the rest of the heart, signaling the heart (cardiac) muscle to contract and pump blood. The SA node generates electrical impulses that start each heartbeat. Sick sinus syndrome (also known as sinus node dysfunction) is an abnormality of the sinoatrial (SA) node, which is an area of specialized cells in the heart that functions as a natural pacemaker. The heart and digestive issues develop at the same time, usually by age 20. The disorder also impairs the rhythmic muscle contractions that propel food through the intestines (peristalsis), causing a digestive condition called intestinal pseudo-obstruction. CAID disrupts the normal rhythm of the heartbeat affected individuals have a heart rhythm abnormality called sick sinus syndrome. Chronic atrial and intestinal dysrhythmia (CAID) is a disorder affecting the heart and the digestive system.
