Myocardial infarctions go along with biomechanical stress, i.e. stretching of muscle fibres, and the expression of certain marker molecules. We tested if two of those markers, endothelin-1 (ET-1) and growth differentiation factor 15 (GDF-15), can be used as immunohistochemical markers for myocardial ischaemia/infarctions. The study included experiments with an animal model, the isolated perfused Langendorff heart, as well as the investigation of human tissue samples drawn during autopsies. The overall picture of our results showed that GDF-15 is very sensitive and expressed very fast, not only as a consequence of ischaemia/infarctions, but also under other circumstances...

RATIONALE: Short-term mechanical circulatory support is increasingly used in the management of cardiogenic shock, but data from controlled studies are sparse. Thus, real-life data on complication rates and predictors of adverse outcome are important. OBJECTIVE: The objective of this study was to analyse the experience with Impella devices in the management of profound cardiogenic shock. METHODS AND RESULTS: A retrospective study of 109 consecutive patients with severe shock after myocardial infarction, acute heart failure, or cardiac surgery...

OBJECTIVE: To review the literature systematically and perform meta-analyses to address these questions: 1) Is there evidence that self-measured blood pressure (BP) without other augmentation is superior to office-based measurement of BP for achieving better BP control or for preventing adverse clinical outcomes that are related to elevated BP? 2) What is the optimal target for BP lowering during antihypertensive therapy in adults? 3) In adults with hypertension, how do various antihypertensive drug classes differ in their benefits and harms compared with each other as first-line therapy? METHODS: Electronic literature searches were performed by Doctor Evidence, a global medical evidence software and services company, across PubMed and EMBASE from 1966 to 2015 using key words and relevant subject headings for randomized controlled trials that met eligibility criteria defined for each question...

The heart is extremely sensitive to ischaemic injury. During an acute myocardial infarction (AMI) event, the injury is initially caused by reduced blood supply to the tissues, which is then further exacerbated by an intense and highly specific inflammatory response that occurs during reperfusion. Numerous studies have highlighted the central role of the NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) inflammasome in this process. The inflammasome, an integral part of the innate immune system, is a macromolecular protein complex that finely regulates the activation of caspase 1 and the production and secretion of powerful pro-inflammatory cytokines such as IL-1β and IL-18...

In patients with ST-segment elevation myocardial infarction (STEMI), it is unclear if combined assessment of left ventricular end-diastolic pressure (LVEDP) and left ventricular ejection fraction (LVEF) improves prediction of major adverse cardiac events (MACE). We analyzed data from 266 STEMI patients who underwent successful percutaneous coronary intervention and subsequent left ventriculography (LVG). Patients were divided into 4 groups, as follows: Group 1, LVEDP < 21 mmHg and LVEF ≥ 55%; Group 2, LVEDP < 21 mmHg and LVEF < 55%; Group 3, LVEDP ≥ 21 mmHg and LVEF ≥ 55%; and Group 4, LVEDP ≥ 21 mmHg and LVEF < 55%...

BACKGROUND: Studies comparing percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery in patients with multivessel coronary artery disease (CAD) have shown lower repeat revascularization rates in patients who undergo CABG. The reason remains unclear. METHODS: We identified patients with multivessel CAD who received CABG or PCI enrolled in the Duke Databank for Cardiovascular Disease (2003 to 2012). We compared the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) between the two groups...

BACKGROUND: Advancing age is a prominent risk factor for atrial fibrillation (AF). Shorter telomere length is a biomarker of biological aging, but the link between shorter telomere length and increased risk of AF remains unclear. We examined the association between shorter leukocyte telomere length (LTL) and incident AF. METHODS AND RESULTS: We included AF-free participants from the observational Framingham Heart Study Offspring cohort from 1995 to 1998, who had LTL measurements...

Background : Clinical trials have shown cardiovascular benefits and potential risks from sodium glucose co-transporter 2 inhibitors (SGLT2i). Trials may have limited ability to address individual endpoints or safety concerns. Methods : We performed a population-based cohort study among type 2 diabetes patients with established cardiovascular disease newly initiated on antihyperglycemic agents (AHAs) within the US Department of Defense Military Health System between 4/1/2013 and 12/31/2016. Incidence rates, hazard ratios (HRs), and 95% confidence intervals (CIs) for time to first composite endpoint of all-cause mortality (ACM) and hospitalization for heart failure (HHF) event, major adverse cardiovascular events (MACE; defined as ACM, nonfatal myocardial infarction, and nonfatal stroke), and individual endpoints were evaluated using conditional Cox models comparing new SGLT2i users with other AHAs...

D Chassard, E Verspyck
Between 2010 and 2012, 29 maternal deaths were caused by cardiovascular disease, i.e. an overall maternal mortality ratio of 1.2 per 100,000 live births. Deaths occurred in pre-existing heart disease (n=19), peripartum cardiomyopathy (n=5), or arterial rupture (n=5). Care was considered non-optimal in three of five patients with congenital heart disease and due to delayed management by specialized teams. Pregnant patients with heart disease should be considered to be at high risk of mortality or severe cardiovascular complications and therefore reoriented as soon as possible to a perinatal center with the expertise of these pathologies...

BACKGROUND: Acute myocardial infarction (AMI) might lead to left ventricular remodeling. Adequate myocardial perfusion is critical to prevent this adverse remodeling. Quantitative myocardial blush evaluator (QuBE) software, available on-line, is a simple analysis tool which enables the precise quantification of myocardial perfusion in the infarct area immediately after interventional treatment. The aim of this study was to assess whether the results of QuBE analysis might predict the development of HF in AMI patients in 3 year-long follow-up...

BACKGROUND/AIMS: Cholecystokinin (CCK) is expressed in cardiomyocytes and may also play an important role in cardiovascular regulation. Clinical studies have shown that plasma CCK levels are an independent marker of cardiovascular mortality in cardiac disease. However, whether the development of postinfarction heart failure is associated with changes in CCK expression is unknown. METHODS: To investigate CCK expression patterns and the association between CCK expression and heart functional parameters, we randomized male Sprague-Dawley rats into myocardial infarction (MI) or sham operation (SO) groups...

Abnormal activity of the renin-angiotensin-aldosterone system plays a causal role in the development of hypertension, atherosclerosis, and associated cardiovascular events such as myocardial infarction, stroke, and heart failure. As both a vasoconstrictor and a proinflammatory mediator, angiotensin II (Ang II) is considered a potential link between hypertension and atherosclerosis. However, a role for Ang II-induced inflammation in atherosclerosis has not been clearly established, and the molecular mechanisms and intracellular signaling pathways involved are not known...

Background -The long-term probability of developing atrial fibrillation (AF) considering genetic predisposition and clinical risk factor burden is unknown. Methods -We estimated lifetime risk of AF in individuals from the community-based Framingham Heart Study. Polygenic risk for AF was derived using a score of approximately 1,000 AF-associated single nucleotide polymorphisms. Clinical risk factor burden was calculated for each individual using a validated risk score for incident AF comprised of height, weight, systolic and diastolic blood pressure, current smoking status, antihypertensive medication use, diabetes, history of myocardial infarction, and history of heart failure...
