#1
REVIEW
Eldad Tzahor, Kenneth D Poss
The human heart is continually operating as a muscular pump, contracting, on average, 80 times per minute to propel 8000 liters of blood through body tissues each day. Whereas damaged skeletal muscle has a profound capacity to regenerate, heart muscle, at least in mammals, has poor regenerative potential. This deficiency is attributable to the lack of resident cardiac stem cells, combined with roadblocks that limit adult cardiomyocytes from entering the cell cycle and completing division. Insights for regeneration have recently emerged from studies of animals with an elevated innate capacity for regeneration, the innovation of stem cell and reprogramming technologies, and a clearer understanding of the cardiomyocyte genetic program and key extrinsic signals...

REVIEW
Francesco Pelliccia, Juan Carlos Kaski, Filippo Crea, Paolo G Camici
Originally described by Japanese authors in the 1990s, Takotsubo syndrome (TTS) generally presents as an acute myocardial infarction characterized by severe left ventricular dysfunction. TTS, however, differs from an acute coronary syndrome because patients have generally a normal coronary angiogram and left ventricular dysfunction, which extends beyond the territory subtended by a single coronary artery and recovers within days or weeks. The prognosis was initially thought to be benign, but subsequent studies have demonstrated that both short-term mortality and long-term mortality are higher than previously recognized...

Hypereosinophilia may be due to several aetiologies. Cardiac complications are not uncommon, whatever the causes. Clinical presentations of hypereosinophilic cardiac diseases may vary widely from asymptomatic form to fatal necrotic myocarditis or irreversible restrictive cardiomyopathy. As a major cause of morbidity and mortality, diagnosis of cardiac involvement is crucial. Until recently the diagnosis was exclusively based on cardiac biopsy. Nowadays, multimodal cardiac imaging, including echocardiography and cardiac magnetic resonance imaging, is the cornerstone of the diagnosis...

BACKGROUND: Routine stress testing is commonly used after percutaneous coronary intervention (PCI) to detect in-stent restenosis or suboptimal procedure results; however, recent studies suggest that such testing is rarely indicated. Our main objectives were to assess temporal trends in utilization of stress testing and to determine factors associated with its use. METHODS: We conducted an observational study involving all patients who had undergone PCI in Ontario, Canada, from Apr...

Supraventricular and ventricular arrhythmias are common among patients with chronic obstructive pulmonary disease (COPD). Multiple factors can contribute to the development of arrhythmias in patients with exacerbation of the disease, including: respiratory or heart failure, hypertension, coronary disease and also medications. In the present study we seek to determine the prevalence of cardiac arrhythmias and risk factors among patients with exacerbation of COPD. The study was a retrospective evaluation of 2753 24-h Holter recordings of patients hospitalized in 2004-2016...

Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e. g. blood chemistry, ECG, spirometry, chest x‑ray) can contribute to a reduction of perioperative risk is often not very well known or is controversial. Similarly, there is considerable uncertainty among anesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication...

Impaired left atrial emptying fraction (LAEF) is an important predictor of mortality in patients with heart failure. As it may reflect increased LV wall stress, it might predict ventricular arrhythmia (VA) specifically. This study evaluated the predictive value of LAEF assessed with cardiovascular magnetic resonance (CMR) imaging with respect to appropriate device therapy (ADT) for VA and compared its role with CMR assessed scar size and other risk factors. In total, 229 patients (68% male, 63 ± 10 years, 61% ischemic cardiomyopathy) with LV ejection fraction ≤35% who underwent CMR and implantable cardioverter defibrillator (ICD) implantation for primary prevention in 2005 to 2012 were included...

BACKGROUND: Heart rate has been associated with prognosis in patients with heart failure with reduced ejection fraction (HFREF) and sinus rhythm; whether this also holds true in patients with atrial fibrillation (AF) is unknown. HYPOTHESIS: To evaluate cardiac rhythm and baseline heart rate and the influence of outcome in patients with HFREF enrolled in the Cardiac Insufficiency Bisoprolol Study II. METHODS: In total, 2539 patients were stratified according to their baseline heart rhythm (AF or sinus rhythm) and into quartiles of heart rate (≤70 bpm, 71-78 bpm, 79-90 bpm, and >90 bpm)...

Osteoprotegerin (OPG) is a glycoprotein that is a representative of the tumor necrosis factor-α receptor superfamily. Information about the possible role of OPG in the development of cardiovascular diseases has begun to appear in the literature in recent years. This review discusses the role of increasing the level of OPG in the development and progression of atherosclerosis and as a consequence of coronary heart disease and chronic heart failure.

BACKGROUND: National practice guidelines do not provide clear recommendations on combination pharmacological regimens to reduce cardiothoracic surgery (CTS) postoperative atrial fibrillation (POAF). OBJECTIVE: This study examines if there is a reduction in POAF rates after implementing a perioperative prophylaxis guideline that includes amiodarone, β-blockers, and high-intensity statins. METHODS: Data were retrospectively collected on 400 adults (200 patients pre-guideline implementation and 200 patients post-guideline implementation) with a CHA2DS2-VASc (Congestive Heart Failure, Hypertension, Age, Diabetes Mellitus, and Vascular Disease) score of at least 3 points after CTS...

Background -It is currently unknown whether intensive blood pressure (BP) lowering beyond that recommended would lead to more lowering of the risk of Left ventricular hypertrophy (LVH) in patients with hypertension, and whether reducing the risk of LVH explains the reported cardiovascular disease (CVD) benefits of intensive BP lowering in this population. Methods -This analysis included 8,164 participants (mean age 67.9 years, 35.3% women, 31.2% blacks) with hypertension but no diabetes from the Systolic Blood Pressure Intervention (SPRINT) Trial; 4,086 randomly assigned to intensive BP lowering (target systolic BP<120mmHg) and 4,078 assigned to standard BP lowering (target systolic BP <140mmHg)...

Type 2- diabetes mellitus (T2DM) represents a major risk factor for cardiovascular complications and mortality. Strict glucose control in the early course of the disease prevents cardiovascular complications only in the long run. Non-medical therapies (diet, exercise, body weight reduction) bear little evidence for positive cardiovascular effects.Bariatric surgery is not number one choice in therapy of T2DM. Metformin seems to provide positive cardiovascular effects. Insulin seems to be cardiovascular neutral, as well as the DPP4-inhibitors Saxagliptin, Sitagliptin and Alogliptin...

In the setting of mechanical circulatory support devices, including ventricular assist devices, extracorporeal membrane oxygenation, intraaortic balloon pumps, and the total artificial heart, the spectral Doppler waveform is significantly altered, reflecting systemic hemodynamic changes. As the prevalence of these devices increases, a better understanding of both the devices themselves and their associated Doppler ultrasound findings is necessary for accurate image interpretation. This article reviews the clinical indications, pathophysiology, and sonographic findings of these devices, with emphasis on the variation in arterial Doppler waveforms that can be seen with normal function, as well as the major complications...
