Trends in modes of death in heart failure over the last two decades: less sudden death but cancer deaths on the rise.
2019
AIMS Better management of heart failure (HF) over the past two decades has improved survival, mainly by reducing the incidence of death due to cardiovascular (CV) causes. Deaths due to non-CV causes, particularly cancer, may be increasing. This study explored the modes of death of consecutive patients who attended a HF clinic over 17 years. METHODS AND RESULTS A total of 935 deaths were ascertained from 2002 to 2018 among 1876 patients (mean age 65.8 ± 12.5 years, 75% men, left ventricular ejection fraction < 50%) admitted to our HF clinic. Median follow-up was 4.2 years [1.9-7.8]. Mode of death was curated from patient health records and verified by the Catalan and Spanish health system da…
Outcomes of Patients With Asymptomatic Aortic Stenosis Followed Up in Heart Valve Clinics
2018
International audience; Importance - The natural history and the management of patients with asymptomatic aortic stenosis (AS) have not been fully examined in the current era. Objective - To determine the clinical outcomes of patients with asymptomatic AS using data from the Heart Valve Clinic International Database. Design, setting, and participants - This registry was assembled by merging data from prospectively gathered institutional databases from 10 heart valve clinics in Europe, Canada, and the United States. Asymptomatic patients with an aortic valve area of 1.5 cm2 or less and preserved left ventricular ejection fraction (LVEF) greater than 50% at entry were considered for the prese…
Subcortical somatosensory evoked potentials after median nerve and posterior tibial nerve stimulation in high cervical cord compression of achondropl…
2008
Abstract Children with achondroplasia may have high cervical myelopathy from stenosis of the cranio-cervical junction resulting in neurological disability and an increased rate of sudden death. To detect myelopathy we recorded somatosensory evoked potentials after median nerve (MN) and posterior tibial nerve (PTN) stimulation in 77 patients with achondroplasia aged 0.3–17.8 years (mean 2.7 years). In addition to the conventional technique of recording the cortical components and the central conduction time (CCT) we employed non-cephalic and mastoid reference electrodes to record the subcortical waveforms N13b and P13 (MN-SEP) as well as P30 (PTN-SEP), respectively, which are generated near …
A bio-clinical approach for prediction of sudden cardiac death in outpatients with heart failure: The ST2-SCD score
2019
Sudden cardiac death (SCD) is one of the main modes of death in heart failure (HF) patients and its prediction remains a real challenge. Our aim was to assess the incidence of SCD at 5 years HF contemporary managed outpatients, and to find a simple prediction model for SCD.SCD was considered any unexpected death, witnessed or not, occurring in a previously stable patient with no evidence of worsening HF or any other cause of death. A competing risk strategy was adopted using the Fine-Gray method of Cox regressions analyses that considered other causes of death as the competing event.The derivation cohort included 744 consecutive outpatients (72% men, age 67.9 ± 12.2 years, left ventricular …
Abnormal subcortical somatosensory evoked potentials indicate high cervical myelopathy in achondroplasia
1999
Children with achondroplasia may have high cervical myelopathy due to stenosis of the cranio-cervical junction resulting in neurological disability and an increased rate of sudden death. To detect myelopathy we recorded somatosensory evoked potentials (SEPs) after median nerve stimulation in 30 patients with achondroplasia aged 13 months to 18 years (mean 6 years). In addition to the conventional technique of recording the cortical N20 and the central conduction time (CCT), we employed a noncephalic reference electrode recording the subcortical waveforms N13b and P13, generated near the cranio-cervical junction. The findings were related to the clinical status and MRI results. Eighteen pati…
Twenty-four-hour ambulatory heart rate and organ damage in primary hypertension.
2010
The relationship between basal heart rate (HR) and the occurrence of myocardial ischemia, sudden death, cardiovascular mortality have been described. Therefore, further studies are warranted to evaluate the behaviour of heart rate in different scenarios. We sought to determine whether ambulatory heart rate is associated with the presence of target organ damage (TOD) in hypertensive patients.Crossectional study of essential hypertensive patients in whom a twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed. The relationship between TOD and 24 hour ambulatory heart rate (HR) was analyzed.Five hundred and sixty-six patients with arterial hypertension were included (55.8%…
Heart rate turbulence for guiding electric therapy in patients with cardiac failure
2009
It is well-known that a reduction of the cardiac frequency variability, measurable with the Heart Rate Variability (HRV) system, is an indirect expression of the sympathetic-autonomic tone. Another index, Heart Rate Turbulence (HRT), has been recently suggested as a possible unit of measurement for the sympathetic-autonomic tone: this system allows to estimate the baro-reflex response of the carotid arteries to an early ventricular extra-systole by analysing heart rate variations induced by a premature beat.In our research we have analyzed this phenomenon in patients affected by moderate or severe cardiac failure. In particular, we divided 110 patients into two arms: subjects with or withou…
Aneurysms of the coronary arteries in infants and children. A review, and report of six cases.
1977
In recent years large numbers of the so-called “mucocutaneous lymph node syndrome” or “Kawasaki's disease” have been described by Japanese workers, but instances of this disorder are only now being reported as isolated cases by European or North American physicians. The disease has, therefore, been considered to be a new entity. One of its most striking features is the development of aneurysms of the coronary arteries in infants or children, which may lead to sudden death. Aneurysms of the coronary arteries in childhood are rare, and hence it was considered relevant to report six such cases, and to examine their possible relationship to Kawasaki's disease. The pathological changes underlyin…
The Jervell and Lange-Nielsen syndrome.
1991
Deafness and electrocardiographic changes (prolongation of the Q-T interval and inversion of the T wave) with a clinical picture of syncopal attacks and sudden death, were described as a distinct syndrome by Jervell and Lange-Nielsen in 1957. The syndrome is inherited as an autosomal recessive trait. In this study, all the cases reported since 1957 and their proposed prevalence are reviewed. The authors describe the 4 cases they have studied, all of which presented congenital sensorineural hearing loss and electrocardiographic changes characteristic of the syndrome. The relatively high number of cases they have encountered casts doubt on literature that states that the syndrome occurs more …
Sudden infant death caused by a ruptured coronary aneurysm during acute phase of atypical Kawasaki disease
2001
This article describe's a case of atypical Kawasaki disease (AKD) with lack of typical clinical signs and rapid fatal course in a 2-month-old infant, who 1 week before hospitalization demonstrated rhinitis, coughing without fever, and later conjunctival hyperemia and allergic exanthema on chest and arms. On admittance, labwork highlighted the following: leukocytosis, thrombocytosis, elevated sedimentation rate, and positive C-reactive protein. General conditions remained mediocre for 7 days until sudden death occurred. The autopsy confirmed death caused by cardiac tamponade caused by a ruptured inflammated aneurysm of the left anterior descending coronary artery. We believe that the current…
