Myocardial infarction and short- or long-term risk of a subsequent cancer diagnosis: A Danish Nationwide Cohort Study.

Background: Growing evidence suggests that myocardial infarction (MI) may be a marker of cancer risk, but many aspects of this relation are poorly understood. We therefore examined the short- and long-term risk of incident cancer in patients presenting with MI.

Methods: Using nationwide population-based Danish health registries, we identified all patients with a first-time diagnosis of MI (1995-2021) and followed them for up to 28 years for any subsequent diagnosis of cancer.

The combined impact of migraine and gestational diabetes on long-term risk of premature myocardial infarction and stroke: A population-based cohort study.

Objective: To examine the combined impact of migraine and gestational diabetes mellitus (GDM) on the risks of premature (persons aged ≤60 years) major adverse cardiovascular and cerebrovascular events (MACCE) based on a composite endpoint of fatal and non-fatal myocardial infarction (MI) and stroke.

Background: Migraine and GDM are risk factors for cardiovascular disease. It is unknown how the combination of migraine and GDM may affect cardiovascular disease risk.

Association of Autoimmune Diseases With Coronary Atherosclerosis Severity and Ischemic Events.

Background: Some autoimmune diseases carry elevated risk for atherosclerotic cardiovascular disease (ASCVD), yet the underlying mechanism and the influence of traditional risk factors remain unclear.

Objectives: This study sought to determine whether autoimmune diseases independently correlate with coronary atherosclerosis and ASCVD risk and whether traditional cardiovascular risk factors modulate the risk.

Methods: The study included 85,512 patients from the Western Denmark Heart Registry undergoing coronary computed tomography angiography.

Short-Chain Fatty Acid Butyrate Is an Inotropic Agent With Vasorelaxant and Cardioprotective Properties.

Background: The heart can metabolize the microbiota-derived short-chain fatty acid butyrate. Butyrate may have beneficial effects in heart failure, but the underlying mechanisms are unknown. We tested the hypothesis that butyrate elevates cardiac output by mechanisms involving direct stimulation of cardiac contractility and vasorelaxation in rats.

Invasively Measured Aortic Systolic Blood Pressure and Office Systolic Blood Pressure in Cardiovascular Risk Assessment in CKD.

Introduction: Central aortic blood pressure (BP) could be a better risk predictor than brachial BP. This study examined whether invasively measured aortic systolic BP improved outcome prediction beyond risk prediction by conventional cuff-based office systolic BP in patients with and without chronic kidney disease (CKD).

Methods: In a prospective, longitudinal cohort study, aortic and office systolic BPs were registered in patients undergoing elective coronary angiography (CAG).

Coronary computed tomography angiography derived fractional flow reserve and risk of recurrent angina: A 3-year follow-up study.

Background: The association between coronary computed tomography angiography (CTA) derived fractional flow reserve (FFR) and risk of recurrent angina in patients with new onset stable angina pectoris (SAP) and stenosis by CTA is uncertain.

Methods: Multicenter 3-year follow-up study of patients presenting with symptoms suggestive of new onset SAP who underwent first-line CTA evaluation and subsequent standard-of-care treatment. All patients had at least one ≥30 ​% coronary stenosis.

Circulating 3-hydroxy butyrate predicts mortality in patients with chronic heart failure with reduced ejection fraction.

Aims: In patients with chronic heart failure with reduced ejection fraction (HFrEF), myocardial ketone metabolism is increased and short-term treatment with the ketone body 3-hydroxy butyrate (3-OHB) has beneficial haemodynamic effects. In patients with HFrEF, we investigated whether the level of circulating 3-OHB predicted all-cause mortality and sought to identify correlations between patient characteristics and circulating 3-OHB levels.

Methods And Results: We conducted a cohort study in 218 patients with HFrEF.

Effects of ketone body 3-hydroxybutyrate on cardiac and mitochondrial function during donation after circulatory death heart transplantation.

Normothermic regional perfusion (NRP) allows assessment of therapeutic interventions prior to donation after circulatory death transplantation. Sodium-3-hydroxybutyrate (3-OHB) increases cardiac output in heart failure patients and diminishes ischemia-reperfusion injury, presumably by improving mitochondrial metabolism. We investigated effects of 3-OHB on cardiac and mitochondrial function in transplanted hearts and in cardiac organoids.

Combined Impact of Migraine and Pregnancy-Induced Hypertension on Long-term Risk of Premature Myocardial Infarction and Stroke.

Background And Objectives: Migraine and pregnancy-induced hypertension (PIH) are known to increase cardiovascular risk on their own. However, evidence is limited on the combined impact of migraine and PIH on risk of cardiovascular disease. The aim of this study was to examine the combined impact of migraine and PIH on risk of premature (age 60 years and younger) major adverse cardiovascular and cerebrovascular events (MACCE), a composite end point consisting of myocardial infarction, stroke, or death due to one of these diseases.

Cohort Profile: Better Health in Late Life.

Purpose: Humans are living longer and may develop multiple chronic diseases in later life. The Better Health in Late Life cohort study aims to improve our understanding of the risks and outcomes of multimorbidity in the Danish population.

Methods: A randomly-selected sample of Danish residents who were 50-65 years of age received a questionnaire and an invitation to participate in this study.

Health position paper and redox perspectives on reactive oxygen species as signals and targets of cardioprotection.

The present review summarizes the beneficial and detrimental roles of reactive oxygen species in myocardial ischemia/reperfusion injury and cardioprotection. In the first part, the continued need for cardioprotection beyond that by rapid reperfusion of acute myocardial infarction is emphasized. Then, pathomechanisms of myocardial ischemia/reperfusion to the myocardium and the coronary circulation and the different modes of cell death in myocardial infarction are characterized.

Remote Ischemic Conditioning for Acute Stroke: The RESIST Randomized Clinical Trial.

Importance: Despite some promising preclinical and clinical data, it remains uncertain whether remote ischemic conditioning (RIC) with transient cycles of limb ischemia and reperfusion is an effective treatment for acute stroke.

Objective: To evaluate the effect of RIC when initiated in the prehospital setting and continued in the hospital on functional outcome in patients with acute stroke.

Design, Setting, And Participants: This was a randomized clinical trial conducted at 4 stroke centers in Denmark that included 1500 patients with prehospital stroke symptoms for less than 4 hours (enrolled March 16, 2018, to November 11, 2022; final follow-up, February 3, 2023).

Prognostic Value of Coronary CT Angiography-derived Fractional Flow Reserve on 3-year Outcomes in Patients with Stable Angina.

Background The prognostic value of coronary CT angiography (CTA)-derived fractional flow reserve (FFR) beyond 1-year outcomes and in patients with high levels of coronary artery calcium (CAC) is uncertain. Purpose To assess the prognostic value of coronary CTA-derived FFR test results on 3-year clinical outcomes in patients with coronary stenosis and among a subgroup of patients with high levels of CAC. Materials and Methods This study represents a 3-year follow-up of patients with new-onset stable angina pectoris who were consecutively enrolled in the Assessing Diagnostic Value of Noninvasive CT-FFR in Coronary Care, known as ADVANCE (ClinicalTrials.

Ketone body 3-hydroxybutyrate elevates cardiac output through peripheral vasorelaxation and enhanced cardiac contractility.

The ketone body 3-hydroxybutyrate (3-OHB) increases cardiac output and myocardial perfusion without affecting blood pressure in humans, but the cardiovascular sites of action remain obscure. Here, we test the hypothesis in rats that 3-OHB acts directly on the heart to increase cardiac contractility and directly on blood vessels to lower systemic vascular resistance. We investigate effects of 3-OHB on (a) in vivo hemodynamics using echocardiography and invasive blood pressure measurements, (b) isolated perfused hearts in Langendorff systems, and (c) isolated arteries and veins in isometric myographs.

Migraine and risk of premature myocardial infarction and stroke among men and women: A Danish population-based cohort study.

Background: Migraine carries risk of myocardial infarction (MI) and stroke. The risk of premature MI (i.e.

Hypercontractile Cardiac Phenotype in Mice with Migraine-Associated Mutation in the Na,K-ATPase α-Isoform.

Two α-isoforms of the Na,K-ATPase (α and α) are expressed in the cardiovascular system, and it is unclear which isoform is the preferential regulator of contractility. Mice heterozygous for the familial hemiplegic migraine type 2 (FHM2) associated mutation in the α-isoform (G301R; α mice) have decreased expression of cardiac α-isoform but elevated expression of the α-isoform. We aimed to investigate the contribution of the α-isoform function to the cardiac phenotype of α hearts.

Hemodynamic Effects of Ketone Bodies in Patients With Pulmonary Hypertension.

Background Pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) are debilitating diseases with a high mortality. Despite emerging treatments, pulmonary vascular resistance frequently remains elevated. However, the ketone body 3-hydroxybutyrate (3-OHB) may reduce pulmonary vascular resistance in these patients.

Augmented Ouabain-Induced Vascular Response Reduces Cardiac Efficiency in Mice with Migraine-Associated Mutation in the Na, K-ATPase α-Isoform.

Heterozygous mice (α mice) for the migraine-associated mutation (G301R) in the Na,K-ATPase α-isoform have decreased expression of cardiovascular α-isoform. The α mice exhibit a pro-contractile vascular phenotype associated with decreased left ventricular ejection fraction. However, the integrated functional cardiovascular consequences of this phenotype remain to be addressed in vivo.

Low-load blood flow-restricted resistance exercise produces fiber type-independent hypertrophy and improves muscle functional capacity in older individuals.

Low-load blood flow-restricted resistance exercise (BFRRE) constitutes an effective means to produce skeletal muscle hypertrophy. Nonetheless, its applicability to counteract the age-related skeletal muscle decay at a cellular level, is not clear. Therefore, we investigated the effect of BFRRE on muscle fiber morphology, integrated muscle protein synthesis, muscle stem cells (MuSCs), myonuclear content, and muscle functional capacity in healthy older individuals.

Long-Term Follow-Up After Acute Myocardial Infarction According to Beta-Blocker Dose.

Objective: Our purpose was to examine the association between beta-blocker dose and mortality following acute myocardial infarction.

Methods: This nationwide cohort study enrolled all patients admitted for first-time acute myocardial infarction in Denmark between July 1, 2004 and December 31, 2014, using the Danish National Patient Registry. Patients alive 15 days after admission were followed until death, emigration, or December 31, 2014.
