The most common causes of chronic liver disease in the developed world-nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH)-are the hepatic manifestations of an insulin-resistant state that is linked to visceral adiposity and systemic inflammation. NAFLD and NASH lead to an expansion of epicardial adipose tissue and the release of proinflammatory adipocytokines that cause microcirculatory dysfunction and fibrosis of the adjoining myocardium, resulting in atrial fibrillation as well as heart failure with a preserved ejection fraction (HFpEF). ⋯ Interventions include 1) weight loss by caloric restriction, bariatric surgery, or intensive exercise, and 2) drugs that ameliorate fat-mediated inflammation in both the liver and heart (eg, statins, metformin, sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide-1 receptor agonists, and pioglitazone). Patients with NAFLD or NASH commonly have an inflammation-related atrial and ventricular myopathy, which may contribute to symptoms and long-term outcomes.

Pulmonary manifestations of inflammatory bowel disease are increasingly recognized in patients with ulcerative colitis and Crohn's disease. Most commonly, incidental abnormalities are noted on chest imaging or pulmonary function tests. ⋯ We review the presenting symptoms, workup, and management for several of the more common forms of inflammatory bowel disease-related pulmonary disease. Increased awareness of the spectrum of extraintestinal inflammatory bowel disease will help providers more readily recognize this phenomenon in their own patients and more comprehensively address the protean sequelae of inflammatory bowel disease.

Review Meta Analysis
Cholesterol Lowering and Stroke: No Longer Room for Pleiotropic Effects of Statins - Confirmation from PCSK9 Inhibitor Studies.
The relationship between cholesterol levels and stroke has been much less clear than the relationship between cholesterol levels and coronary heart disease. This is likely mostly due to the inadequate power of older studies and the low intensity of cholesterol-lowering interventions available at the time. Because a reduction in stroke has been, conversely, clearly observed in trials with statins, for long "pleiotropic" effects of such drugs, unrelated to cholesterol lowering, have been invoked. In a previous analysis of all randomized trials of cholesterol-lowering treatments reporting on stroke we had, however, reached the conclusion that any cholesterol lowering is related to a significant reduction of stroke, in a relationship that appeared to exist for both statin and nonstatin cholesterol-lowering interventions. Outcome results of the FOURIER trial with evolocumab, SPIRE-1 and -2 with bococizumab, and ODYSSEY OUTCOMES trial with alirocumab now offer the opportunity of clearly confirming or confuting this concept. ⋯ These findings offer definitive proof that the pure total (and low-density lipoprotein) cholesterol lowering, with any available lipid-lowering intervention, reduces stroke risk proportional to the extent of cholesterol reduction, without the need of invoking "pleiotropic" effects of any such treatment.

Restricting dietary sodium is a common recommendation given by clinicians to patients with heart failure and is one supported by current guidelines. However, the quality of evidence for this recommendation is suboptimal, and there is no consensus on the optimal level of sodium intake. ⋯ Nevertheless, sodium restriction is routinely recommended and remains a cornerstone of heart failure and blood pressure therapy. In this review we discuss the pros and cons of sodium restriction for patients with heart failure from the current literature.

Meta Analysis
Predictors of Mortality in Myocardial Infarction and Nonobstructed Coronary Arteries: A Systematic Review and Meta-Regression.
The long-term mortality of patients with myocardial infarction and nonobstructed coronary arteries (MINOCA) remains poorly defined. This study aimed to determine the long-term mortality of patients with MINOCA and to identify potential prognostic determinants of long-term outcome. ⋯ The long-term mortality after MINOCA is lower than that in patients with myocardial infarction and obstructive coronary artery disease, but it is not trivial. Reduced ejection fraction, nonobstructive coronary artery disease, use of beta-blockers during follow up and ST depression on the admission electrocardiogram are significant predictors of long-term prognosis.
