Background Whether orthostatic hypotension (OH) is a risk factor for cardiovascular morbidity and death is uncertain. Currently available evidence derives from non-homogeneous and partly ambiguous studies. Objective We aimed at assessing the relationship between OH and death or major adverse cardiac and cerebrovascular events (MACCEs) by integrating results of previous studies. Methods We performed a meta-analysis of prospective observational studies reporting on the association between prevalent OH, mortality, and incident MACCE, published from 1966 through 2013. Mantel–Haenszel pooled estimates of relative risk (RR) and 95% confidence intervals (CIs) for all-cause death were assessed as the primary endpoint at the longest follow-up; incident coronary heart disease (CHD), heart failure (HF), and stroke were assessed as secondary endpoints. We also performed post hoc subgroup analyses stratified by age and a meta-regression analysis. Results We identified a total of 13 studies, including an overall population of 121 913 patients, with a median follow-up of 6 years. Compared with the absence of OH, the occurrence of OH was associated with a significantly increased risk of all-cause death (RR 1.50; 95% CI 1.24–1.81), incident CHD (RR 1.41; 95% CI 1.22–1.63), HF (RR 2.25; 95% CI 1.52–3.33), and stroke (RR 1.64; 95% CI 1.13–2.37). When analysed according to age, pooled estimates of RR (95% CI) for all-cause death were 1.78 (1.25–2.52) for patients <65 years old, and 1.26 (0.99–1.62) in the older subgroup. Conclusion Orthostatic hypotension is associated with a significantly increased risk of all-cause death, incident CHD, HF, and stroke.

New evidence suggests that non-alcoholic fatty liver disease (NAFLD) has a strong multifaceted relationship with diabetes and metabolic syndrome, and is associated with increased risk of cardiovascular events, regardless of traditional risk factors, such as hypertension, diabetes, dyslipidemia, and obesity. Given the pandemic-level rise of NAFLD—in parallel with the increasing prevalence of obesity and other components of the metabolic syndrome—and its association with poor cardiovascular outcomes, the question of how to manage NAFLD properly, in order to reduce the burden of associated incident cardiovascular events, is both timely and highly relevant. This review aims to summarize the current knowledge of the association between NAFLD and cardiovascular disease, and also to discuss possible clinical strategies for cardiovascular risk assessment, as well as the spectrum of available therapeutic strategies for the prevention and treatment of NAFLD and its downstream events.

The long-term prognosis of angina in patients without obstructive coronary artery disease (CAD) is uncertain. To assess the incidence of long-term adverse outcomes in such patients. We searched PubMed, Cochrane Library, the Embase database, and the Clinical Trials Registry for studies published in English until January 2017, assessing the composite primary outcome of all-cause death and non-fatal myocardial infarction using random-effects models to estimate pooled incidences. We identified 54 studies, reporting outcomes in overall 35 039 patients (mean age 56, male/female ratio 0.51, 99 770 person-years) with angina and no obstructive CAD. After a median follow-up of 5 years (interquartile range 3–7 years), the pooled incidence of the primary outcome was 0.98/100 person-years [95% confidence interval (CI) 0.77–1.19%], with considerable heterogeneity among studies (I² = 91%, P < 0.001). The primary outcome was associated with prevalent dyslipidaemia (P = 0.016), diabetes (P = 0.035), and hypertension (P = 0.016). Studies enrolling patients with less-than-obstructive CAD showed a higher incidence of the primary outcome (1.32/100 person-years, 95% CI 1.02–1.62) compared with studies including only patients with ‘entirely normal’ coronary arteries (0.52/100 person-years, 95% CI 0.34–0.79, respectively; P < 0.01). The incidence of the primary outcome did not differ significantly between studies enrolling only patients with documented myocardial ischaemia and those studies enrolling patients regardless of presence of ischaemia. However, ischaemia documented by non-invasive imaging techniques was associated with a higher incidence of events (P = 0.02). Overall, these patients, however, suffered from a high incidence of recurrent hospitalization. Angina without obstructive CAD has a heterogeneous prognosis. A main determinant of major adverse events is the presence of ‘some’ coronary atherosclerosis, with unequivocal myocardial ischaemia being associated with worse clinical outcomes. Patients’ quality of life is also worsened by the high incidence of hospitalization, angina recurrence, and repeated coronary angiography.

Excessive trabeculation, often referred to as "noncompacted" myocardium, has been described at all ages, from the fetus to the adult. Current evidence for myocardial development, however, does not support the formation of compact myocardium from noncompacted myocardium, nor the arrest of this process to result in so-called noncompaction. Excessive trabeculation is frequently observed by imaging studies in healthy individuals, as well as in association with pregnancy, athletic activity, and with cardiac diseases of inherited, acquired, developmental, or congenital origins. Adults with incidentally noted excessive trabeculation frequently require no further follow-up based on trabecular pattern alone. Patients with cardiomyopathy and excessive trabeculation are managed by cardiovascular symptoms rather than the trabecular pattern. To date, the prognostic role of excessive trabeculation in adults has not been shown to be independent of other myocardial disease. In neonates and children with excessive trabeculation and normal or abnormal function, clinical caution seems warranted because of the reported association with genetic and neuromuscular disorders. This report summarizes the evidence concerning the etiology, pathophysiology, and clinical relevance of excessive trabeculation. Gaps in current knowledge of the clinical relevance of excessive trabeculation are indicated, with priorities suggested for future research and improved diagnosis in adults and children.

Orthostatic hypotension (OH), a common, often overlooked, disorder with many causes, is associated with debilitating symptoms, falls, syncope, cognitive impairment, and risk of death. Chronic OH, a cardinal sign of autonomic dysfunction, increases with advancing age and is commonly associated with neurodegenerative and autoimmune diseases, diabetes, hypertension, heart failure, and kidney failure. Management typically involves a multidisciplinary, patient-centered, approach to arrive at an appropriate underlying diagnosis that is causing OH, treating accompanying conditions, and providing individually tailored pharmacological and nonpharmacological treatment. We propose a novel streamlined pathophysiological classification of OH; review the relationship between the cardiovascular disease continuum and OH; discuss OH-mediated end-organ damage; provide diagnostic and therapeutic algorithms to guide clinical decision making and patient care; identify current gaps in knowledge and try to define future research directions. Using a case-based learning approach, specific clinical scenarios are presented highlighting various presentations of OH to provide a practical guide to evaluate and manage patients who have OH.
