Cystic fibrosis can be described as a condition which arises when a mutation occurs in the CTFR gene takes place. The CTFR gene codes for CTFR proteins. CTFR proteins can be described as proteins present in the transmembrane. These proteins are transmembrane regulators. In cystic fibrosis, the person is not able to produce the CTFR protein at all or makes abnormal CTFR protein. As a result, a thick and sticky mucus is generated.
Fatty substances such as cholestrol and saturated fats may be deposited on the inner surface of the coronary arteries. This narrows the lumen of these arteries and increases blood pressure. Such an affected artery develops a rough inner surface. This increases the risk of a blood clot being trapped in the artery. A blood clot that forms in an artery is called a thrombosis. Blood supply to the heart muscles can be greatly reduced due to the blockage of the coronary arteries. This can cause a heart attack. Hope this helps!
