Surgical therapy for ischemic heart failure: Single-center experience with surgical anterior ventricular restoration

ObjectivesOur objectives were (1) to report operative and long-term mortality in patients submitted to anterior surgical ventricular restoration, (2) to report changes in clinical and cardiac status induced by surgical ventricular restoration, and (3) to report predictors of death in a large cohort of patients operated on at San Donato Hospital, Milan, Italy.MethodsA total of 1161 consecutive patients (83% men, 62 ± 10 years) had anterior surgical ventricular restoration with or without coronary artery bypass grafting and with or without mitral repair/replacement. A complete echocardiographic study was performed in 488 of 1161 patients operated on between January 1998 and October 2005 (study group). The indication for surgery was heart failure in 60% of patients, angina, and/or a combination of the two.ResultsThirty-day cardiac mortality was 4.7% (55/1161) in the overall group and 4.9% (24/488) in the study group. Determinants of hospital mortality were mitral valve regurgitation and need for a mitral valve repair/replacement. Mitral regurgitation (>2+) associated with a New York Heart Association class greater than II and with diastolic dysfunction (early-to-late diastolic filling pressure >2) further increases mortality risk. Global systolic function improved postoperatively: ejection fraction improved from 33% ± 9% to 40% ± 10% (P < .001); end-diastolic and end-systolic volumes decreased from 211 ± 73 to 142 ± 50 and 145 ± 64 to 88 ± 40 mL, respectively (P < .001) early after surgery. New York Heart Association functional class improved from 2.7 ± 0.9 to 1.6 ± 0.7 (P < .001) late after surgery. Long-term survival in the overall population was 63% at 120 months.ConclusionsSurgical ventricular restoration for ischemic heart failure reduces ventricular volumes, improves cardiac function and functional status, carries an acceptable operative mortality, and results in good long-term survival. Predictors of operative mortality are mitral regurgitation of 2+ or more, New York Heart Association class greater than II, and diastolic dysfunction (early-to-late diastolic filling pressure >2)

Potential therapeutic effects of natural heme oxygenase-1 inducers in cardiovascular diseases.

Significance: Many physiological effects of natural antioxidants, their extracts or their major active components, have been reported in recent decades. Most of these compounds are characterized by a phenolic structure, similar to that of α-tocopherol, and present antioxidant properties that have been demonstrated both in vitro and in vivo. Polyphenols may increase the capacity of endogenous antioxidant defenses and modulate the cellular redox state. Such effects may have wide-ranging consequences for cellular growth and differentiation. Critical Issues: The majority of in vitro and in vivo studies conducted so far have attributed the protective effect of bioactive polyphenols to their chemical reactivity toward free radicals and their capacity to prevent the oxidation of important intracellular components. One possible protective molecular mechanism of polyphenols is nuclear factor erythroid 2-related factor (Nrf2) activation, which in turn regulates a number of detoxification enzymes. Recent Advances: Among the latter, the heme oxygenase-1 (HO-1) pathway is likely to contribute to the established and powerful antioxidant/anti-inflammatory properties of polyphenols. In this context, it is interesting to note that induction of HO-1 expression by means of natural compounds contributes to prevention of cardiovascular diseases in various experimental models. Future Directions: The focus of this review is on the role of natural HO-1 inducers as a potential therapeutic strategy to protect the cardiovascular system against various stressors in several pathological conditions

Extrathoracic heart in northern Cameroon: a case report

Sternal clefts, ectopia cordis, and Cantrell's pentalogy continue to be very rare congenital anomalies in pediatric surgery. The prenatal diagnosis is easily made with ultrasound by visualizing the heart outside the thoracic cavity. Ectopia cordis is frequently associated with other congenital defects involving multiple organ systems. We report a case of ectopia cordis with successful surgical correction on a 7 months old child from northern Cameroon

Occurrence, aetiology and challenges in the management of congestive heart failure in sub-Saharan Africa: experience of the Cardiac Centre in Shisong, Cameroon

Introduction: The aim of the study was to investigate the occurrence, the aetiology and the management of congestive heart failure in the cardiac centre of the St. Elizabeth catholic general hospital Shisong in Cameroon. Methods: Between November 2002 and November 2008, a population of 8121 patients was consulted in the referral cardiac centre of St. Elizabeth Catholic General Hospital. Of these patients, 462 were diagnosed with congestive heart failure according to the modified Framingham criteria for the diagnosis of heart failure. Complementary investigations used to confirm and establish the aetiology of the disease were the chest X-ray, electrocardiography, bi-dimensional Doppler echocardiography. Results: The results showed that the occurrence of congestive heart failure in our centre was 5.7%. Congestive heart failure was diagnosed in 198 females and 264 males, aged between 8 and 86 years old (42.5&plusmn;18 years old). Post rheumatic valvulopathies (14.6%) and congenital heart diseases (1.9%) were the first aetiologic factor of congestive heart failure in the young, meanwhile cardiomyopathies (8.3%) in elderly followed by hypertensive cardiomyopathy (4.4%). Congestive heart failure was also seen in adults with congenital heart diseases in 0.01%. In this zone of Cameroon, we discovered that HIV cardiomyopathy (1.6%) and Cor pulmonale (8%) were represented, aetiological factors not mentioned in previous studies conducted in urban areas of Cameroon. The mean duration of hospital stay for the compensation treatment was thirteen days, ranging between 7 and 21 days), the mortality being 9.2%. All the medications recommended for the treatment of congestive heart failure are available in our centre but many patients are not compliant to the therapy or cannot afford them. Financial limitation is causing the exacerbation of the disease and premature death. Conclusion: Our data show a high incidence of congestive heart failure mainly due to post rheumatic valvulopathies in young patients in our centre. National program to fight against rheumatic fever and complications are of great urgency in our country. The compensation treatment of congestive heart failure is challenging in our milieu, characterized by poor compliance and financial limitations.Key words: Congestive heart failure, cardiac centre Shisong, valvulopathies, cardiomyopathy, Cameroon, Hypertension, heart failur

The Importance of Being the Morning Case in Adult Cardiac Surgery: A Propensity-Matched Analysis

Objectives: The quality of the outcome after cardiac surgery with cardiopulmonary bypass depends on the patient demographics, co-morbidities, complexity of the surgical procedure, and expertise of surgeons and the whole staff. The purpose of the present study is to analyze the timing of surgery (morning vs afternoon) with respect to morbidity and mortality in adult cardiac surgery. Methods: The primary end-point was the incidence of major morbidity defined according to a modified Society of Thoracic Surgeon criterion. We consecutively included all the adult (&gt; 18 years) patients receiving a cardiac surgery operation at our Institution. Results: From 2017 through 2019 a total of 4,003 cardiac surgery patients were operated. With a propensity-matching technique a final patient population of 1600 patients was selected, with 800 patients in the first-case surgery group and 800 in the second-case surgery group. Patients in the second-case group had a major morbidity rate of 13% vs 8.8% in the first-case group (P = 0.006), and a higher rate of 30-days mortality (4.1% vs 2.3%, P = 0.033). After correction for EuroSCORE and operating surgeon, the second-case group confirmed a higher rate of major morbidity (odds ratio 1.610, 95% confidence interval 1.16-2.23, P = 0.004). Conclusion: Our study suggests that patients operated as second cases are exposed to an increased morbidity and mortality probably due to fatigue, loss of attention and hurriedness in the operating room, and decreased human resources in the intensive care unit

A qualitative study exploring behavioural change intervention in Congenital Heart Disease

IntroductionMedical advancements have significantly improved survival of patients with Congenital Heart Disease (CHD). Consequently, an aging CHD population are more susceptible to cardiac-related complications and co-morbidities.Early intervention, with individually-tailored, patient-centred approaches targeting physical activity, diet and stress, can reduce these modifiable risks. Lifestyle Intervention Programmes (LIP) are safe, cost-effective interventions, aiming to promote positive health behaviour change. CHD LIP efficacy research is limited.ObjectiveThis study aims to explore patients’ expectations and experiences to better identify determinants of patient adherence and aspects of LIP that need developing.MethodsQualitative study using semi-structured interviews. Group 1 included seven patients who had not taken part in a LIP to establish views and expectations of LIP. Group 2 included five patients who participated in 3-month pilot LIP at Guy's and St Thomas' to gather feedback on their experience.ResultsThree key themes were identified from Group 1 data: Expectations of Lifestyle Intervention Programme and Intentions to Engage, Views about Online Support for Lifestyle Intervention Programme, Patient Anxieties about Exercise Damaging their Heart. Four key themes were identified from Group 2 data: Insufficient Dietary Information, Brilliant Intentions Marred by Barriers, Pertinence of Plans to Patients, Positive Patient Experiences and Outcomes.ConclusionsThis study provides new insight into beliefs, expectations and experiences of patients with CHD. Findings support the value of LIP for CHD and inform recommendations for LIP development including need for health psychology, dietetic support, more education, greater focus on techniques to address barriers to adherence and scope for specifically-designed App

The T.O.S.C.A. Project: Research, Education and Care

Despite recent and exponential improvements in diagnostic- therapeutic pathways, an existing “GAP” has been revealed between the “real world care” and the “optimal care” of patients with chronic heart failure (CHF). We present the T.O.S.CA. Project (Trattamento Ormonale dello Scompenso CArdiaco), an Italian multicenter initiative involving different health care professionals and services aiming to explore the CHF “metabolic pathophysiological model” and to improve the quality of care of HF patients through research and continuing medical education
