Magnetic Resonance Imaging in the Assessment of the Risk of Sudden Death in Cardiac Sarcoidosis: What Is Extensive or Significant Late Gadolinium Enhancement?

Background: Cardiac sarcoidosis involves a significant but difficult-to-define risk of sudden cardiac death (SCD). Current guidelines recommend consideration of an implantable cardioverter defibrillator for patients with extensive or significant myocardial late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging. However, extensive/significant LGE is not defined.

The Value of Repeat 5-HIAA Measurements as a Predictor of Carcinoid Heart Disease: A Prospective 5-Year Follow-Up Study in Patients with Small Intestinal Neuroendocrine Tumors.

Small intestinal neuroendocrine tumors (SI-NETs) are characterized by carcinoid syndrome and carcinoid heart disease (CHD). The aim of the present study was to identify early risk markers for carcinoid heart disease and survival in a prospective median-term follow-up setting. We measured 5-HIAA and cumulative 5-HIAA exposure (Cum-5-HIAA) based on repeated measurements, proBNP, vascular function, hepatic tumor load, and transthoracic echocardiography (TTE) at baseline and during the median 5-year follow-up.

Heart-healthy diets including phytostanol ester consumption to reduce the risk of atherosclerotic cardiovascular diseases. A clinical review.

The risk of atherosclerotic cardiovascular diseases (ASCVDs) can be reduced by lowering low-density lipoprotein cholesterol (LDL-C) concentrations. Nevertheless, ASCVDs still cause most deaths worldwide. Here, we discuss the prevention of ASCVD and the event risk with a focus on heart-healthy diets, i.

30-Year Trends in the Incidence, Characteristics, and Outcome of Cardiac Sarcoidosis in a Nationwide Cohort.

Background: Cardiac sarcoidosis (CS) is a rare but potentially fatal inflammatory cardiomyopathy.

Objectives: The authors studied temporal changes in the incidence, characteristics, and outcome of CS.

Methods: A retrospective analysis was made of a 30-year nationwide cohort of CS.

The effect of hydroxychloroquine on cholesterol synthesis depends on the profile of cholesterol metabolism. A controlled clinical study.

Background And Aims: Hydroxychloroquine (HCQ) has a variable effect on cholesterol synthesis. To clarify this, we assessed the effect of HCQ on the cholesterol-synthesis pathway in individuals with low and high cholesterol absorption efficiency.

Method: A total of 53 acute myocardial infarction patients with a constant statin dose randomized to receive HCQ or placebo for six months in a double-blind manner, were classified further into low (n = 26) and high (n = 27) cholesterol absorbers based on the median baseline serum cholestanol level.

The effect of hydroxychloroquine on cholesterol metabolism in statin treated patients after myocardial infarction.

Background And Aims: To evaluate the effect of hydroxychloroquine (HCQ) on serum and lipoprotein lipids and serum biomarkers of cholesterol synthesis and absorption in myocardial infarction patients with a high-dose statin.

Methods: Myocardial infarction patients (n = 59) with a constant statin dose were randomized to receive hydroxychloroquine 300 mg (n = 31) or placebo (n = 28) daily for six months and followed up for one year.

Results: Statin reduced total-c (-26 ± 22% in hydroxychloroquine and -28 ± 19% in placebo group, P = 0.

Arterial function, biomarkers, carcinoid syndrome and carcinoid heart disease in patients with small intestinal neuroendocrine tumours.

Purpose: Carcinoid heart disease (CHD) is a life-threatening complication of carcinoid syndrome (CS) characterised by tricuspid regurgitation (TR). However, there is an unmet need for earlier diagnosis of CHD. We cross-sectionally assessed the prevalence and potential predictive or diagnostic markers for CS and CHD in a contemporary cohort of patients with small intestinal neuroendocrine tumours (SI-NETs).

Obesity Does Not Interfere with the Cholesterol-Lowering Effect of Plant Stanol Ester Consumption (as Part of a Heart-Healthy Diet).

Dietary modifications including plant stanol ester consumption are recommended measures to control serum and low-density lipoprotein (LDL)-cholesterol concentrations, but obesity can affect their responses. We investigated whether body mass index (BMI) affects serum cholesterol levels during plant stanol (mainly sitostanol) ester consumption. This ad hoc analysis was based on earlier results of a cross-over, randomized controlled trial of postmenopausal women consuming rapeseed oil-based margarine without or with plant stanol ester (3 g plant stanols/day) for seven weeks.

Non-invasive dye dilution method for measuring an atrial septal defect shunt size.

Aims: Objective of this study was to evaluate the feasibility of the non-invasive dye dilution method to quantify shunt size related to atrial septal defects (ASD).The diagnostic accuracy of shunt size determination in ASD's has been suboptimal with common non-invasive methods. We have previously developed a cost-effective and time-effective non-invasive dye dilution method.

Lowering Low-Density Lipoprotein Cholesterol Concentration with Plant Stanol Esters to Reduce the Risk of Atherosclerotic Cardiovascular Disease Events at a Population Level: A Critical Discussion.

Atherosclerotic cardiovascular diseases (ASCVDs) cause every fifth death worldwide. However, it is possible to prevent the progression of ASCVDs by reducing circulating concentrations of low-density lipoprotein cholesterol (LDL-C). Recent large meta-analyses demonstrated that by reducing the dietary intake of saturated fat and cholesterol, it is possible to reduce the risk of ASCVD events.

Outcome of Cardiac Sarcoidosis Presenting With High-Grade Atrioventricular Block.

Background: Symptomatic high-grade atrioventricular block (AVB) is the most common and often the only presenting manifestation (lone AVB) of cardiac sarcoidosis. Implantation of an intracardiac cardioverter defibrillator instead of a pacemaker is recommended, but the true risk of fatal arrhythmia, one incident to lone AVB in particular, remains poorly known.

Methods: We used Myocardial Inflammatory Diseases in Finland Study Group Registry to analyze the presentations, left ventricular (LV) function, pacemaker therapy, and ventricular arrhythmias in cardiac sarcoidosis.

Serum non-cholesterol sterols and cholesterol metabolism in childhood and adolescence.

Background And Aims: The profile of cholesterol metabolism, i.e., high absorption vs.

Serum noncholesterol sterols in Alzheimer's disease: the Helsinki Businessmen Study.

Cerebral cholesterol metabolism is perturbed in late-onset Alzheimer's disease (AD), but whether also the extracerebral cholesterol metabolism is perturbed is not known. Thus, we studied whole-body cholesterol synthesis and absorption with serum noncholesterol sterols in men without AD (n = 114) or with (n = 18) "pure" AD (no concomitant atherosclerotic cardiovascular disease) in a long-term cohort (the Helsinki Businessmen Study) of home-dwelling older men without lipid-lowering drugs and on their habitual home diet. Serum lipids did not differ between AD and controls, but age was higher (78 ± 1 vs 74 ± 0.
