Familial Hypercholesterolemia and Its Current Diagnostics and Treatment Possibilities: A Literature Analysis.

Familial hypercholesterolemia (FH) is a common, inherited disorder of cholesterol metabolism. This pathology is usually an autosomal dominant disorder and is caused by inherited mutations in the APOB, LDLR, and PCSK9 genes. Patients can have a homozygous or a heterozygous genotype, which determines the severity of the disease and the onset age of cardiovascular disease (CVD) manifestations. The incidence of heterozygous FH is 1: 200-250, whereas that of homozygous FH is 1: 100.000-160.000. Unfortunately, FH is often diagnosed too late and after the occurrence of a major coronary event. FH may be suspected in patients with elevated blood low-density lipoprotein cholesterol (LDL-C) levels. Moreover, there are other criteria that help to diagnose FH. For instance, the Dutch Lipid Clinical Criteria are a helpful diagnostic tool that is used to diagnose FH. FH often leads to the development of early cardiovascular disease and increases the risk of sudden cardiac death. Therefore, early diagnosis and treatment of this disease is very important. Statins, ezetimibe, bile acid sequestrants, niacin, PCSK9 inhibitors (evolocumab and alirocumab), small-interfering-RNA-based therapeutics (inclisiran), lomitapide, mipomersen, and LDL apheresis are several of the available treatment possibilities that lower LDL-C levels. It is important to say that the timeous lowering of LDL-C levels can reduce the risk of cardiovascular events and mortality in patients with FH. Therefore, it is essential to increase awareness of FH in order to reduce the burden of acute coronary syndrome (ACS).

Anaemia in Heart Failure Patients, Associated with Angiotensin - Renin - Aldosterone System Altering Medications.

Heart failure (HF) remains one of the most common diseases and one of the major causes of death worldwide. HF is often associated with other chronic diseases, most commonly with anemia. Anemia increases patients' mortality and lowers their quality of life. There are a few pathophysiological mechanisms that explain anemia in patients with HF - hemodilution, absolute or functional iron deficiency, activation of the inflammatory cascade, chronic kidney disease, and impaired erythropoietin production and activity. Moreover, congestive HF is often treated with angiotensin-converting enzyme inhibitors and aldosterone receptors blockers, which could be linked to the development of anemia.
