Cardiac failure

To assess the T1 and extracellular volume (ECV) maps of left ventricle (LV) of patients with non-ischemic heart failure (NIHF) by cardiac MRI. In NIHF with preserved WT of LV, texture analysis of T1 and ECV maps showed difference in the mean value of native T1 and texture features, which is promising as a base for machine learning with future larger cohort.

Video - assisted thoracoscopic minimally invasive mitral valve replacement, associated with fast tract anesthesia and early extubation, was accepted in clinical practice. At Viet Duc University Hospital, we began to use this technique in January 2021. The purpose of this study is to evaluate the initial results.

Cardiac hypertrophy (CH), leading to cardiac failure is due to chronic metabolic alterations occurring during cellular stress. Besides the already known relationship between oxidative stress and CH, there are implications of reductive stress leading to CH. This study attempted to develop reductive stress-based CH rat model using n-acetyl-L-cysteine (NAC), a glutathione agonist that was compared with typical isoproterenol (ISO) induced CH model.

Obesity is a known risk factor for induction of myocardial infarction, but, paradoxically, may also confer a protective effect against subsequent remodeling leading to heart failure. In this study, we investigated the effect of leptin, the product of the obese (ob) gene, on cardiomyocyte apoptosis, a well-characterized component of cardiac remodeling after myocardial infarction.

1/ THỂ NÀO LÀ SUY TIM SUNG HUYẾT (CONGESTIVE HEART FAILURE) ? Đó là sự loạn năng tim (cardiac dysfunction) khiến tim không thể hoạt động như một cái bơm để thỏa mãn những nhu cầu tuần hoàn của bệnh nhân. Do đó sự sung huyết phổi (pulmonary congestion) xảy ra, và khi vấn đề nghiêm trọng sẽ đưa tới phù phổi (pulmonary edema).

Timing of Cardiac Surgery In general, when indications for surgical treatment of infective endocarditis are identified, surgery should not be delayed simply to permit additional antibiotic therapy, since this course of action increases the risk of death (Table 118-6). Delay is justified only when infection is controlled and congestive heart failure is fully compensated with medical therapy. After 14 days of recommended antibiotic therapy, excised valves are culture-negative in 99% and 50% of patients with streptococcal and S. aureus endocarditis, respectively.

Table 118-5 Indications for Cardiac Surgical Intervention in Patients with Endocarditis Surgery required for optimal outcome Moderate to severe congestive heart failure due to valve dysfunction Partially dehisced unstable prosthetic valve Persistent bacteremia despite optimal antimicrobial therapy Lack of effective microbicidal therapy (e.g., fungal or Brucella endocarditis) S.

Intracardiac Surgical Indications Most surgical interventions are warranted by intracardiac findings, detected most reliably by TEE. Because of the highly invasive nature of prosthetic valve endocarditis, as many as 40% of affected patients merit surgical treatment. In many patients, coincident rather than single intracardiac events necessitate surgery. Congestive Heart Failure Moderate to severe refractory congestive heart failure caused by new or worsening valve dysfunction is the major indication for cardiac surgical treatment of endocarditis.

Antibiotic Therapy after Cardiac Surgery Bacteria visible in Gram-stained preparations of excised valves do not necessarily indicate a failure of antibiotic therapy. Organisms have been detected on Gram's stain—or their DNA has been detected by PCR—in excised valves from 45% of patients who have successfully completed the recommended therapy for endocarditis. In only 7% of these patients are the organisms, most of which are unusual and antibiotic resistant, cultured from the valve. Despite the detection of organisms or their DNA, relapse of endocarditis after surgery is uncommon.

Cardiac Manifestations Although heart murmurs are usually indicative of the predisposing cardiac pathology rather than of endocarditis, valvular damage and ruptured chordae may result in new regurgitant murmurs. In acute endocarditis involving a normal valve, murmurs are heard on presentation in only 30–45% of patients but ultimately are detected in 85%. Congestive heart failure develops in 30–40% of patients; it is usually a consequence of valvular dysfunction but occasionally is due to endocarditis-associated myocarditis or an intracardiac fistula.

Nonimmunologic Reactions Fluid Overload Blood components are excellent volume expanders, and transfusion may quickly lead to volume overload. Monitoring the rate and volume of the transfusion and using a diuretic can minimize this problem. Hypothermia Refrigerated (4°C) or frozen (–18°C or below) blood components can result in hypothermia when rapidly infused. Cardiac dysrhythmias can result from exposing the sinoatrial node to cold fluid. Use of an in-line warmer will prevent this complication.

Erythroderma (Table 54-2) Erythroderma is the term used when the majority of the skin surface is erythematous (red in color). There may be associated scale, erosions, or pustules as well as shedding of the hair and nails. Potential systemic manifestations include fever, chills, hypothermia, reactive lymphadenopathy, peripheral edema, hypoalbuminemia, and high-output cardiac failure. The major etiologies of erythroderma are (1) cutaneous diseases such as psoriasis and dermatitis (Table 54-3); (2) drugs; (3) systemic diseases, most commonly CTCL; and (4) idiopathic.
