1. Epidemiology of MAFLD and risk of CVD | |
1.1 MAFLD is associated with an increased prevalence of CVD events compared with the non-MAFLD population | A |
1.2 MAFLD is associated with an increased incidence of nonfatal CVD events compared with the non-MAFLD population | A |
1.3 MAFLD is associated with an increased incidence of CVD mortality compared with the non-MAFLD population | A |
1.4 The incidence of fatal and/or nonfatal CVD events in individuals with MAFLD is higher compared to that in the NAFLD population | B |
1.5 MAFLD predicts better the risk of CVD events than NAFLD | B |
1.6 Increasing severity of liver fibrosis is associated with higher CVD risk | A |
1.7 Hepatic steatosis is associated with an increase in CVD risk | A |
1.8 MAFLD is a risk factor for CVD events even after adjustment for traditional cardiovascular risk factors | A |
2. Epidemiology of MAFLD and CVD outcomes | |
2.1 MAFLD is associated with greater carotid-artery intima-media thickness and increased risk of carotid atherosclerotic plaques | A |
2.2 MAFLD is associated with atherosclerotic CVD events such as acute coronary syndromes | U |
2.3 MAFLD is associated with increased risk of cardiac arrhythmias (mainly permanent atrial fibrillation) | A |
2.4 MAFLD is associated with abnormal myocardial function and structure | A |
3. Pathophysiological mechanisms linking MAFLD and CVD | |
3.1 MAFLD and CVD share multiple cardiometabolic risk factors, such as systemic low-grade inflammation, endothelial dysfunction, increased oxidative stress, insulin resistance and an atherogenic lipoprotein profile | A |
3.2 Activation of the renin-angiotensin system is one of the mechanistic links between MAFLD and CVD risk | A |
3.3 Some shared genetic polymorphisms (e.g., PNPLA3 I148M, and TM6SF2 E167K) may affect the risk of both MAFLD and CVD | A |
3.4 Gut microbiota may play a role in both MAFLD and CVD | A |
4. MAFLD and primary prevention of CVD | |
4.1 Carotid ultrasonography should be considered in most patients with MAFLD to improve CVD risk assessment | B |
4.2 In CVD risk assessment, MAFLD may be considered a CVD risk factor | A |
4.3 Screening for MAFLD should be considered in most patients with CVD | A |
5. Managing MAFLD and the risk of CVD | |
5.1 Clinicians who manage patients with MAFLD should target cardiometabolic risk factors (overweight/obesity, diabetes, dyslipidemia and hypertension) | U |
5.2 Lifestyle intervention (including a healthy dietary pattern, weight loss and regular physical exercise) is associated with improvement in both MAFLD and CVD | U |
5.3 Alcohol avoidance of any type or amount is advisable in patients with MAFLD and CVD | A |
5.4 Treatment with GLP-1RAs is beneficial in MAFLD patients with coexisting T2DM and may reduce CVD outcomes | U |
5.5 Treatment with SGLT-2 inhibitors is beneficial in MAFLD patients with coexisting T2DM and may reduce CVD outcomes | U |
5.6 Treatment with pioglitazone is beneficial in MAFLD patients and may reduce CVD outcomes, but potential adverse effects (e.g. weight gain, edema and worsening of pre-existing congestive heart failure) should be kept in mind | A |
5.7 Statins (if required for the treatment of dyslipidemia or CVD risk reduction) should be prescribed for patients with MAFLD even with modestly elevated serum liver enzyme levels (< 3 ULN) | A |
5.8 Bariatric surgery (if required in severely obese patients with MAFLD) improves liver histology features and reduces CVD risk | U |
