Sudden death risk markers for patients with left ventricular ejection fractions greater than 40%

The major burden of sudden cardiac death (SCD) in patients with heart disease occurs in those with a left ventricular ejection fraction  > 40%. Although the annual risk of SCD may be lower in these patients compared to those with lower LVEF, their lifetime cumulative risk of SCD may be greater due to a better overall prognosis. It is plausible that those with LVEF > 40% who are at highest risk of life-threatening arrhythmia will benefit from implantable cardioverter defibrillators. Features that identify patients with a LVEF > 40% at high risk of SCD are urgently needed.

Purpose of review Orthotopic heart transplantation (OHT) significantly improves morbidity and mortality in patients with end-stage heart disease. Despite advances in surgical technique, immunosuppressive therapies, and patient monitoring, long-term risk of arrhythmias and sudden cardiac death (SCD) in the denervated heart remains unchanged. Recent findings SCD is responsible for approximately 10% of all posttransplant deaths with a pooled incidence rate of 1.30 per 100 person years and is strongly associated with cardiac allograft vasculopathy (CAV). Risk factors for SCD and CAV include higher donor age, younger recip...

Abstract Introduction: Controversies regarding the use of beta-blocker in chronic obstructive pulmonary disease (COPD) have been longstanding and based on inconsistent data. COPD and cardiovascular disease have many shared risk factors and potentially overlapping pathophysiologic mechanisms. Beta-blockers, a mainstay of treatment in ischemic heart disease, congestive heart failure, and cardiac arrhythmia, remain underutilized in COPD patients despite considerable evidence of safety. Furthermore, observational studies indicated potential benefits of beta-blockers in COPD via a variety of possible mechanisms. Recent...

CONCLUSIONS: In this depictive study of 85 fatal cases of COVID-19, most cases were male aged over 50 years old with noncommunicable chronic diseases. The majority of the patients died of multiple organ failure. Early onset of shortness of breath may be used as an observational symptom for COVID-19 exacerbations. Eosinophilopenia may indicate a poor prognosis. The combination of anti-microbial drugs did not offer considerable benefit to the outcome of this group of patients.

Left ventricular noncompaction cardiomyopathy is a heart disease with relevant potential complications including heart failure, life-threatening arrhythmias, and embolic events. In order to prevent adverse outcomes, it is crucial to appropriately recognize and manage this cardiomyopathy. In this paper, we report the main clinical presentations and imaging modalities used for diagnosis, including echocardiography and magnetic resonance imaging. We highlight the role of a comprehensive functional cardiac evaluation and the possible prognostic implications of both systolic and diastolic dysfunction. Furthermore, we summarize ...

Common indication for echocardiography – MCQ – Answer Which of the following is not a common indication for echocardiography? – Correct answer: d) Analysis of cardiac arrhythmia Analysis of cardiac arrhythmia is better done using an ECG. In patients with cardiac arrhythmia, echocardiography is useful in looking for underlying structural heart disease. Echocardiography can be used to assess arrhythmias in fetus when ECG is not feasible. But it is not very accurate and is quite cumbersome, time consuming process. Back to question

sco Salvo Tyrosine kinase inhibitors (TKIs), the treatment of choice for chronic myeloid leukemia (CML), can be associated to cardiovascular (CV) adverse events (AEs). A case/non-case study was performed using AE reports registered in the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database to compare the risk of CV event reports related to TKIs indicated in the management of chronic myeloid leukemia (CML). Disproportionality of CV event-related TKIs was computed using the Reporting Odds Ratio (ROR) as a measure of potential risk increase. Nilotinib accounts for more than half of reported ...

Conclusion: The most frequent isolated valve surgery in Brazil is the aortic valve replacement by conventional open access and the rheumatic disease is still the main etiology for valve surgery. The BYPASS Registry has a fundamental role to provide information on the profile of patients with valve heart disease in our country in order to delineate adequate strategies for health promotion and resource allocation for cardiac surgery.

Discussion Tachycardia is a rapid heart rate that is above normal for age and level of exertion. Tachycardia is common, particularly sinus tachycardia due to normally encountered circumstances such as pain, fever or exercise. It is usually a normal physiologic process but sustained tachycardia often indicates a potentially abnormal underlying cause. Sinus tachycardia has a rapid heart rate with normal P waves and P-R intervals and variations from moment to moment and respiration. Generally it is not over 200 beats/minute. Vagal stimulation can slow the heart rate; this is a gradual slowing, not an abrupt slowing seen in ...

In this study, we aimed to analyze sex differences in the comorbidity, therapy, and health services’ use of HF patients. We conducted a cross-sectional study in Aragón (Spain) and described the characteristics of 17,516 patients with HF. Women were more frequent (57.4 vs. 42.6%, p < 0.001) and older (83 vs. 80 years, p < 0.001) than men, and presented a 33% lower risk of 1-year mortality (p < 0.001). Both sexes showed similar disease burdens, and 80% suffered six or more diseases. Some comorbidities were clearly sex-specific, such as arthritis, depression, and hypothyroidism in wom...
