Determinants of acceptance of patients with heart failure and their informal caregivers regarding an interactive decision-making system: a qualitative study.

Objective: Heart failure is a growing challenge to healthcare systems worldwide. Technological solutions have the potential to improve the health of patients and help to reduce costs. Acceptability is a prerequisite for the use and a successful implementation of new disruptive technologies.

Artificial intelligence supported patient self-care in chronic heart failure: a paradigm shift from reactive to predictive, preventive and personalised care.

Heart failure (HF) is one of the most complex chronic disorders with high prevalence, mainly due to the ageing population and better treatment of underlying diseases. Prevalence will continue to rise and is estimated to reach 3% of the population in Western countries by 2025. It is the most important cause of hospitalisation in subjects aged 65 years or more, resulting in high costs and major social impact.

Are there also negative effects of social support? A qualitative study of patients with inflammatory bowel disease.

Objective: Social support is considered an important resource in coping with chronic conditions. By conducting a series of interviews with people who suffer from inflammatory bowel disease (IBD), we received the impression that social support in face-to-face or online communication could also be a source of stress and strain. The aim of our study was to better understand and describe possible negative effects of social support.

"And then you start to loose it because you think about Nutella": The significance of food for people with inflammatory bowel disease - a qualitative study.

Background: Many patients with inflammatory bowel disease strongly believe that food or certain food products heavily influence the symptoms or even trigger acute flare-ups. Unfortunately, there is no generalizable information for these patients, and therefore no effective diet has been identified to date.

Methods: The narrative interviews we used for this study provide the basis for the German website www.

Effectiveness of nifedipine GITS in combination with atenolol in chronic stable angina.

Nifedipine gastrointestinal therapeutic system (GITS) is a once-daily formulation of nifedipine that provides stable plasma concentrations over the entire 24 h dosing interval. Two-hundred and one patients with Canadian Cardiovascular Society class II to III angina who were on 50 mg of atenolol yet still experiencing angina symptoms were randomized to receive either placebo or nifedipine GITS 30, 60 or 90 mg/day. After four weeks of treatment, the changes in time from baseline to onset of 1 mm ST segment depression in the 183 eligible patients were 26.

Generalized linear least squares method for fast generation of myocardial blood flow parametric images with N-13 ammonia PET.

In this paper, we developed and tested strategies for estimating myocardial blood flow (MBF) and generating MBF parametric images using positron emission tomography (PET), N-13 ammonia, and the generalized linear least square (GLLS) method. GLLS was generalized to the general linear compartment model, modified for the correction of spillover, validated using simulated N-13 ammonia data, and examined using PET data from several patient studies. In comparison to the standard model-fitting procedure, the GLLS method provided similar accuracy and superior computational speed.

Noninvasive quantification of the cerebral metabolic rate for glucose using positron emission tomography, 18F-fluoro-2-deoxyglucose, the Patlak method, and an image-derived input function.

The authors developed and tested a method for the noninvasive quantification of the cerebral metabolic rate for glucose (CMRglc) using positron emission tomography (PET), 18F-fluoro-2-deoxyglucose, the Patlak method, and an image-derived input function. Dynamic PET data acquired 12 to 48 seconds after rapid tracer injection were summed to identify carotid artery regions of interest (ROIs). The input function then was generated from the carotid artery ROIs.

Treatment and outcome of patients with acute myocardial infarction and prior cerebrovascular events in the thrombolytic era: the Israeli Thrombolytic National Survey.

Background: Patients with a history of stroke presenting with acute myocardial infarction (MI) are often excluded from thrombolytic therapy owing to fear of intracranial hemorrhage. Few data, however, are available on the risks vs the benefits of thrombolysis in patients with an acute MI and a prior cerebrovascular event (PCE).

Methods: Data were derived from 2 nationwide surveys of 2012 consecutive patients with acute MI admitted to all 25 coronary care units in Israel during 1992 and 1994.

Plasma lipid oxidation and susceptibility of low-density lipoproteins to oxidation in male patients with stable coronary artery disease.

Objectives: Oxidative modifications of low-density lipoproteins (LDL) are considered to be important in the pathogenesis of atherosclerosis. However, the data on the association between LDL oxidation and severity of clinical manifestations of coronary artery disease (CAD) are contradictory. Previous reports were concerned mostly with unstable angina patients.

Long-term prognosis of patients after a Q wave compared with a non-Q wave first acute myocardial infarction. Data from the SPRINT Registry.

Unlabelled: OBJECTIVE, DESIGN AND PATIENTS: Between August 1981 and July 1983, 5839 consecutive myocardial infarction patients were hospitalized in 13 coronary care units in Israel. The present study examines 10 year survival among 4037 consecutive patients with a first myocardial infarction with either Q or non-Q waves. Demographic and medical data were collected from hospital records, and 1 year clinical follow-up was complete for 99% of hospital survivors.

Calcium antagonists and mortality in patients with coronary artery disease: a cohort study of 11,575 patients.

Objectives: This study sought to establish the risk ratio for mortality associated with calcium antagonists in a large population of patients with chronic coronary artery disease.

Background: Recent reports have suggested that the use of short-acting nifedipine may cause an increase in overall mortality in patients with coronary artery disease and that a similar effect may be produced by other calcium antagonists, in particular those of the dihydropyridine type.

Methods: Mortality data were obtained for 11,575 patients screened for the Bezafibrate Infarction Prevention study (5,843 with and 5,732 without calcium antagonists) after a mean follow-up period of 3.

Lysine-binding species of lipoprotein(a) in coronary artery disease.

Elevated levels of plasma lipoprotein(a) [Lp(a)] have frequently been associated with coronary artery disease (CAD). Recently Lp(a) was fractionated into two species with different affinities for Lysine-Sepharose. The influence of lysine-binding heterogeneity of Lp(a) on its cardiovascular pathogenicity has not previously been studied.

Immediate and long-term prognostic significance of a first anterior versus first inferior wall Q-wave acute myocardial infarction. Secondary Prevention Reinfarction Israeli Nifedipine Trial (SPRINT) Study Group.

Of 3,981 patients with a first Q-wave acute myocardial infarction (AMI), 1,929 (48%) had an anterior and 1,724 (43%) an inferior wall AMI. These 2 groups were well-matched with respect to age, gender and relevant history. The in-hospital mortality rate was 18%, and the 1- and 5-year post-discharge mortality rates were 9 and 25%, respectively, in patients with anterior wall AMI compared with the corresponding rates of 11, 6 and 19% in those with inferior wall AMI (p < 0.

The prognostic significance of angina pectoris preceding the occurrence of a first acute myocardial infarction in 4166 consecutive hospitalized patients.

We examined the role of chronic (greater than 1 month) angina pectoris (AP) before acute myocardial infarction (AMI) in predicting hospital and long-term mortality rates among 4166 patients with first AMIs. The prevalence of AP in these patients was 43%. Chronic AP was more common in women (49%), patients with hypertension (49%), and diabetic patients (49%) than in men and counterparts free of the former conditions (p less than 0.

Long-term prognosis after acute myocardial infarction in patients with left ventricular hypertrophy on the electrocardiogram. SPRINT Study Group.

Among 4,720 consecutive hospital survivors from acute myocardial infarction (AMI) treated in 13 coronary care units between July 1981 and August 1983, the estimated prevalence of electrocardiographic left ventricular (LV) hypertrophy was 6.1%. The prevalence of electrocardiographic LV hypertrophy increased with age and was higher in patients with previous myocardial infarction, angina and systemic hypertension.

Cerebrovascular accident complicating acute myocardial infarction: incidence, clinical significance and short- and long-term mortality rates. The SPRINT Study Group.

Purpose: The purpose of this study was to report the incidence, the antecedents, and the clinical significance of clinically recognized cerebrovascular accidents or transient ischemic attacks (CVA-TIA) complicating acute myocardial infarction.

Patients And Methods: During 1981 to 1983, a secondary prevention study with nifedipine (SPRINT) was conducted in 14 hospitals in Israel among 2,276 survivors of acute myocardial infarction. During the study, demographic, historical, and medical data were collected on special forms for all patients with diagnosed acute myocardial infarction in 13 of these 14 hospitals (the SPRINT registry, n = 5,839).

Monotherapy of stable angina pectoris with bopindolol in comparison with diltiazem.

The efficiency of bopindolol (B) in the treatment of moderate stable angina pectoris was compared with that of diltiazem (D) by clinical evaluation and exercise tolerance. Following washout of previous treatment, patients were randomly assigned to either medication: 16 to D and 15 to B. The initial dose of B was 1 mg once daily, increased after 4 weeks to 2 mg once daily; the respective doses of D were 120 and 240 mg, given in 4 divided doses.

[Echocardiographic diagnosis of anomalous origin of left coronary artery].

Cross sectional and M-mode echocardiography is a well-established noninvasive technique in the diagnosis of dilated cardiomyopathy and is essential in the evaluation of its severity and progress. However, in most cases of dilated cardiomyopathy in children, it does not provide data suggestive of the etiology of the disease. In the rare congenital malformation, anomalous origin of the left coronary artery from the pulmonary artery, the echocardiographic techniques may suggest the diagnosis when the left coronary artery cannot be demonstrated to arise from its usual site, the left coronary sinus (as visualized in the short axis of the aortic root).

Von Willebrand factor and mitral valve prolapse.

The levels of von Willebrand factor (vWF:Ag) were measured in 27 patients with mitral valve prolapse (MVP) and compared to 27 age matched controls. Decreased levels of vWF:Ag (less than 80%) were found in 59% (16/27) of those with MVP compared to only 7% (2/27) of the controls (p less than 0.001).

The scale of myocardial involvement in varicella myocarditis.

Two patients with varicella myocarditis are described. An arrhythmia associated with complete recovery occurred in the first patient whereas intractable congestive heart failure complicated by hemiplegia resulted in a fatal outcome in the other case. We stress the extent of myocardial involvement produced by the herpes zoster virus in the setting of varicella.

Renal excretion of lactate and magnesium in mitral valve prolapse.

A strong positive correlation between urinary magnesium and lactate was found in 17 magnesium-depleted patients with echocardiographically proved mitral valve prolapse. The strong correlation over all the range of urinary magnesium values and the significantly increased excretion of lactate suggest urinary magnesium loss in this syndrome.
