About This Presentation

Description : Check out this medical PowerPoint presentation titled "Atherosclerosis is the liver disease” by Prof. O. Drapkina.

This medical PowerPoint presentation talks about atherosclerosis, a medical condition characterized by the build-up of plaque inside the walls of arteries. The plaque is composed of fatty substances, cholesterol, cellular waste products, and calcium deposits. Over time, the plaque hardens and narrows the arteries, reducing blood flow to organs and tissues. This can lead to various complications such as heart attack, stroke, and peripheral artery disease.

Atherosclerosis can begin in childhood, and its progression is influenced by many factors, including genetics, lifestyle choices such as diet and exercise, smoking, and underlying medical conditions such as high blood pressure, high cholesterol, and diabetes.

Treatment for atherosclerosis may involve lifestyle changes such as regular exercise, healthy eating habits, and quitting smoking. Medications such as statins may be prescribed to lower cholesterol levels and reduce the risk of heart attack and stroke. In some cases, surgery may be necessary to remove or bypass the blocked arteries. Early detection and management of atherosclerosis are crucial for preventing complications and improving outcomes.

Non-alcoholic fatty liver disease NAFLD is probably the most common liver disease in many countries affecting 10% to 24% of the general population. There is a direct correlation between body mass index (BMI) and prevalence and severity of NAFLD. Annals of hepatology 2002; 1(1): January-March: 12-19

Prevalence of NAFLD in Europe Total population (people with normal weight) 15 – 20 % children 20 – 24 % adults – on average 22% Increases with age Found more frequently in men More frequently found among Europeans than Latin Americans Fan, 2009, EASL Congress

Obesity - a major ethiologic factor in NAFLD The prevalence of fatty liver in the general population is about 23% The prevalence among alcoholics reaches 46%, among the obese - 76%, and among alcoholics who are overweight - 95% Consequently, fatty liver is caused by obesity in a greater extent than by alcohol Drapkina OM, Smirin VI, VT Ivashkin Nonalcoholic fatty liver disease - a modernapproach to the problem.

Epicardial fat – fat shell of the heart EF and the myocardium share the same microcirculation, so the epicardial fat should be considered the true visceral fat depot of the heart. Epicardial fat and … steatosis of the heart

Epicardial fat: marker of metabolic syndrome, early vascular damage and diastolic dysfunction Patients with MS had significantly higher epicardial fat thickness than controls (4.95±2.6 and 2.69±1.8 mm, p=0.01). Age, BMI, waist circumference, fasting glucose, HOMA-IR, intima-media thickness were significantly higher in subjects with MS and increased epicardial fat than without, while the echocardiographic diastolic function index early/atrial peak flow (E/A) was significantly lower. At multivariate analysis HOMA-IR remained the independent variable associated with epicardial fat (p=0.04, OR1.8, 95% CI1.037-3.58).

Arterial stiffness and : the Cardio-GOOSE study The study population consisted of 220 participants (123 women), aged between 30 and 70 years, who participated in the GOOSE study. Arterial stiffness was determined by measuring the carotid-femoral pulse wave velocity (PWV) by means of the PulsePen device. Preclinical atherosclerosis was detected by carotid intima-media thickness (IMT) measurement. PWW Norma NAFLD NAFLD+MS

Statins and NAFLD Safety: ↑ AST / ALT in 1-3% of patients There are no convincing data on the relationship between ↑ AST / ALT and histologicallyverified liver damage against statins Atorvastatin (80 mg) reduced the AST / ALT, and possibly reduced steatosis[Gomez-Dominguez, 2006; Kiyici, 2003] Pravastatin (80 mg) reduced ALT [Lewis et al. 2007] Possible mechanisms - Reduction of TNF-alpha, IL-6, CRP, - Reduced delivery of FFA to the liver, the effect on insulin through adiponectin
