Hospitalization for heart failure (HF) places a major burden on healthcare services worldwide, and is a strong predictor of increased mortality especially in the first three months after discharge. Though undesirable, hospitalization is an opportunity to optimize HF therapy and advise clinicians and patients about the importance of continued adherence to HF medication and regular monitoring. The Optimize Heart Failure Care Program (www.optimize-hf.com), which has been implemented in 45 countries, is designed to improve outcomes following HF hospitalization through inexpensive initiatives to improve prescription of appropriate drug therapies, patient education and engagement, and post-discharge planning. It includes best practice clinical protocols for local adaptation, pre- and post-discharge checklists, and 'My HF Passport', a printed and smart phone application to improve patient understanding of HF and encourage involvement in care and treatment adherence. Early experience of the Program suggests that factors leading to successful implementation include support from HF specialists or 'local leaders', regular educational meetings for participating healthcare professionals, multidisciplinary collaboration, and full integration of pre- and post-hospital discharge checklists across care services. The Program is helping to raise awareness of HF and generate useful data on current practice. It is showing how good evidence-based care can be achieved through the use of simple clinician and patient-focused tools. Preliminary results suggest that optimization of HF pharmacological therapy is achievable through the Program, with little new investment. Further data collection will lead to a greater understanding of the impact of the Program on HF care and key indicators of success.
One hundred and eighty-seven patients who had surgical closure of a ventricular septal defect between 1958 and 1975 were followed for up to 21 years. there were 17 late sudden deaths of which eight occurred in completely fit patients while nine were already under medical care. In an attempt to elucidate possible risk factors and reoperative and serial postoperative electrocardiograms of all patients were studied. Fifty-one unselected healthy follow-up patients agreed to 24 hour ambulatory monitoring. Progressive exercise testing (Bruce protocol) was carried out on 31 of them and an additional seven patients. There was a significant correlation between recorded ventricular arrhythmias and conduction defects, particularly progressive conduction defects. Transient complete heart block carried a bad prognosis and grade 3-4b ventricular arrhythmias were a major risk factor and recorded in 10 of the 17 patients who died. Long-term postoperative electrocardiographic follow-up is recommended and 24 hour ambulatory monitoring and exercise testing complement the findings of the resting electrocardiogram. The long-term treatment of survivors found to have ventricular arrhythmias must be considered.
Cardiac function was evaluated in 24 children from a Jamaican sickle cell cohort study. Ten patients with sickle cell disease underwent echocardiographic studies on their eighth birthday. The results were compared with 14 age- and sex-matched control children born within hours of the index patients. Left ventricular dimension index (systolic 2.89 +/- 0.31 versus 2.33 +/- 0.42 cm and diastolic 4.70 +/- 0.35 versus 3.64 +/- 0.48 cm, p = 0.001), diastolic volume (79.4 +/- 17.1 versus 60.8 +/- 7.8 ml, p = 0.01), left ventricular mass index (116.3 +/- 3.4 versus 74.3 +/- 15.2 g/m2, p = 0.001) and cardiac index (5.51 +/- 1.32 versus 3.38 +/- 0.85 liters/min per m2 p = 0.001) were significantly increased in patients with sickle cell disease compared with values in control subjects. However, there was no statistically significant difference between the two groups for ejection fraction, velocity of circumferential fiber shortening, percent fractional shortening, systolic time intervals, wall stress and ratio of wall stress-systolic volume. Although two mean ratios of wall stress-systolic volume index were lower in children with sickle cell disease as compared with control subjects (4.0 +/- 0.7 versus 5.4 +/- 1.7, p = 0.02 and 5.9 +/- 1.2 versus 8.3 +/- 2.5, p = 0.005, respectively), the range of ratios remained within normal limits (3.4 to 5.8 in children with sickle cell disease versus 2.8 to 9.5 in controls and 4.2 to 8.3 versus 3.8 to 12.5, respectively). Furthermore, only body surface area predicted group status independent of other variables (p = 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
