REVIEW
Juan José Santos Mateo, María Sabater Molina, Juan Ramón Gimeno Blanes
Hypertrophic cardiomyopathy is the most common inherited cardiovascular disease. It is characterized by increased ventricular wall thickness and is highly complex due to its heterogeneous clinical presentation, several phenotypes, large number of associated causal mutations and broad spectrum of complications. It is caused by mutations in sarcomeric proteins, which are identified in up to 60% of cases of the disease. Clinical manifestations of Hypertrophic Cardiomyopathy include shortness of breath, chest pain, palpitations and syncope, which are related to the onset of diastolic dysfunction, left ventricular outflow tract obstruction, ischemia, atrial fibrillation and abnormal vascular responses...

AIMS: Recent guidelines have advocated for stricter systolic blood pressure (SBP) control in heart failure with preserved ejection fraction (HFpEF), though data regarding the optimal SBP in HFpEF are sparse. METHODS AND RESULTS: We analysed participants from the Americas from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) study with available baseline and 8-week visit SBP data (n = 1645). We related baseline SBP to several efficacy and safety outcomes...

AIMS: The most recent European guidelines have proposed new definitions of pulmonary hypertension (PH) in left heart disease, to better approach the characteristics required to reflect the presence of pulmonary vascular disease. The purpose of this study was to assess whether different haemodynamic definitions of post-capillary PH imply a different reversibility of PH in response to acute vasodilator administration in heart failure patients with reduced ejection fraction and PH (HFrEF-PH)...

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: Ivabradine (IVA) is effective in patients with coronary artery disease (CAD) or systolic heart failure in sinus rhythm. Its action consists in reducing heart rate (HR) and improving the time of left ventricular (LV) diastolic filling. The aim of this study was to evaluate the effects of IVA added to conventional therapy on patients with diastolic heart failure (DHF) and preserved ejection fraction (HFpEF). Methods: We evaluated 25 patients with DHF in the New York Heart Association (NYHA) Class II-III and sinus rhythm...

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...

The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

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...

This study was devised to investigate the effect of coronary artery disease (CAD) without overt signs of heart failure on the cardiovascular responses to muscle metaboreflex activation. We hypothesized that any CAD-induced pre-clinical systolic and/or diastolic dysfunction could impair hemodynamic response to the metaboreflex test. Twelve males diagnosed with CAD without any sign or symptoms of heart failure and 11 age-matched healthy controls (CTL) participated in the study. Subjects performed a post-exercise muscle ischemia (PEMI) test to activate the metaboreflex...

Contemporary imaging modalities offer non-invasive quantification of myocardial deformation; however, they make gross assumptions about internal structure of the cardiac walls. Our aim is to study the possible impact of the trabeculations on the stroke volume, strain and capacity of differently sized ventricles. The cardiac left ventricle is represented by an ellipsoid and the trabeculations by a tissue occupying a fixed volume. The ventricular contraction is modelled by scaling the ellipsoid whereupon the measurements of longitudinal strain, end-diastolic, end-systolic and stroke volume are derived and compared...

The majority of older adults who develop heart failure (HF), particularly older women, have a preserved left ventricular ejection fraction (HFpEF). The prevalence of this syndrome is increasing, and the prognosis is not improving, unlike that of HF with reduced ejection fraction (HFrEF). Individuals with HFpEF have severe symptoms of effort intolerance, poor quality of life, frequent hospitalizations, and greater likelihood of death. Despite the importance of HFpEF, there are numerous major gaps in our understanding of its pathophysiology and management...

BACKGROUND: Coexistence of left ventricular (LV) longitudinal myocardial systolic dysfunction with LV diastolic dysfunction could lead to heart failure with preserved ejection fraction (HFpEF). Diabetes mellitus (DM) is known as a significant factor associated with HFpEF. Although the mechanisms of DM-related LV myocardial injury are complex, it has been postulated that overweight contributes to the development of LV myocardial injury in type 2 diabetes mellitus (T2DM) patients. However, the precise impact of overweight on LV longitudinal myocardial systolic function in T2DM patients remains unclear...

Background: Myocardial dysfunction may contribute to circulatory failure in sepsis. There is growing evidence of an association between left ventricular diastolic dysfunction (LVDD) and mortality in septic patients. Utilizing echocardiography, we know that tissue Doppler imaging (TDI) variables e' and E/e' are reliable predictors of LVDD and are useful measurements to estimate left ventricular (LV) filling pressures. Methods: We conducted a systematic review and meta-analysis to investigate the association of e' and E/e' with mortality of patients with severe sepsis or septic shock...

Pingan Chen, Lina Hou, Yishan Luo, Lushan Chen, Shaonan Li, Xiaoming Lei, Jiankai Huang, Daihong Wu
Background Serum 2-oxoglutarate can reflect the severity of chronic heart failure (CHF) in patients without diabetes. Whether this predictive role persists in type 2 diabetes mellitus (T2DM) patients is unclear. In this study, we investigated this predictive role in T2DM patients and whether 2-oxoglutarate can indicate the diastolic or systolic function of left ventricle. Methods One hundred eighty CHF patients (76 with T2DM) and 66 healthy controls were studied. 2-Oxoglutarate was assayed by liquid chromatography-mass spectrometry/mass spectrometry...

We present the rare case of a patient with pulmonary hypertension in the context of the stiff left atrial syndrome after extensive catheter ablation, a unique constellation characterized by high pulmonary artery and pulmonary artery wedge pressures due to left atrial dysfunction but normal left ventricular end-diastolic pressure, normal mitral valve, and absence pulmonary vein stenosis. This patient was surprisingly oligosymptomatic, however, which may have been due to a persistent post-puncture atrial septal defect, which may have allowed for controlled left atrial decompression, which is in line with the novel concept of the catheter-based creation of an intracardiac shunt as a treatment for heart failure...

BACKGROUND: Metabolic syndrome is a combination of symptoms including obesity, dyslipidaemia, glucose intolerance and hypertension. Oxidative stress appears to be a pathophysiological factor that links these signs and encourages progression towards heart failure and diabetes. Nox4 is a hydrogen peroxide nicotinamide adenine dinucleotide phosphate (NADPH) oxidase isoform - found in various cardiovascular cells and tissues, but also in tissues such as the liver - which is involved in glucose and lipid homeostasis...
