Long-term Mortality Rates (long-term + mortality_rate)
Selected AbstractsFavorable Long-Term Survival in Patients Undergoing Stent PCI of Unprotected Left Main Coronary Artery Compared to Predicted Short-Term Prognosis of CABG Estimated by EuroSCORE: Clinical Determinants of Long-Term OutcomeJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 4 2009RALF LEHMANN M.D. Aims/Methods: The long-term outcome of patients (pts) undergoing percutaneous coronary intervention (PCI) of unprotected left main coronary artery (LMCA) is unclear so far. We prospectively investigated the outcome of 102 consecutive patients who underwent stent PCI of unprotected LMCA. Patients were divided according to clinical indication for PCI: stable coronary artery disease (CAD) (N = 60), NSTEMI (N = 18), STEMI (N = 24). Expected in-hospital mortality of coronary artery bypass grafting (CABG) was calculated using the European System for Cardiac Operative Risk Evaluation (EuroSCORE) and compared to the observed survival rate during long-term follow-up (mean 1.8 ± 1.2 years). Results: The observed 30-day mortality was 1.7% (1/60 pts) in patients with stable CAD, 11% (2/18 pts) in NSTEMI patients, and 13% (3/24 pts) in STEMI patients. The observed mortality was lower than the predicted mortality of CABG as calculated by the logistic EuroSCORE. Using receiver-operator characteristics curves (ROC), EuroSCORE demonstrated a high predictive value for both 30-day mortality as well as 1-year mortality (AUC > 0.8; P < 0.01). Prognostically relevant patient related factors (P < 0.01) included severely reduced left ventricular ejection fraction (HR 3.24), ACS (HR 3.18), STEMI (HR: 3.01), Killip class IV (HR 7.69), occurrence of neoplastic disease (HR 3.97), and elevated CRP (HR 3.86). Conclusions: LMCA-PCI was associated with lower long-term mortality rates compared to the estimated mortality of CABG. This prospective observational study suggests that DES-PCI of unprotected LMCA in "all-comers" can be carried out with reasonable risk. [source] Racial Disparity in Clinical Outcomes Following Primary Percutaneous Coronary Intervention for ST Elevation Myocardial Infarction: Influence of Process of CareJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 3 2007JOSHUA A. JACOBI M.D. Previous studies have shown that compared with white patients, non-white patients with STelevation myocardial infarction (STEMI) have worse clinical outcomes. Differences in co-morbidities, extent and severity of coronary artery disease, health insurance, and socioeconomic status have been identified as possible reasons for this disparity. However, an alternative explanation for such observed disparities in outcomes could be differences in process of care. For example, in most of these studies, non-white patients were less likely to receive reperfusion therapy, and if treated, were more likely to receive thrombolysis than to undergo primary percutaneous coronary intervention (PCI). We hypothesized that if all patients were treated similarly with primary PCI, there would be no difference in clinical outcomes. We analyzed the demographic, angiographic, in-hospital clinical outcomes, and long-term mortality rates of a racially diverse group of patients presenting to the same hospital with STEMI, all of whom were treated with primary PCI. Our data demonstrate that compared with white patients, non-white patients with STEMI who undergo primary PCI have similar in-hospital clinical outcomes and one-year mortality. This suggests that the previously observed differences in mortality rates may be, at least in part, attributable to differences in the process of care, and not solely to differences in patient factors or differential therapeutic effects. [source] Mortality in epilepsy in the first 11 to 14 years after diagnosis: Multivariate analysis of a long-term, prospective, population-based cohortANNALS OF NEUROLOGY, Issue 3 2001Samden D. Lhatoo MRCP The United Kingdom National General Practice Study of Epilepsy is a prospective, population-based study of newly diagnosed epilepsy. A cohort of 792 patients has now been followed for up to 14 years (median follow-up [25th, 75th percentiles] 11.8 years, range 10.6,11.7 years), a total of 11,400 person-years. These data are sufficient for a detailed analysis of mortality in this early phase of epilepsy. Over 70% of patients in this cohort have developed lasting remission from seizures, although the mortality rate in the long term was still twice that of the general population. The standardized mortality ratio (SMR), the number of observed deaths per number of expected deaths, was 2.1 (95% confidence interval [CI] = 1.8, 2.4). Patients with acute symptomatic epilepsy (SMR 3.0; 95% CI = 2.0, 4.3), remote symptomatic epilepsy (SMR 3.7; 95% CI = 2.9, 4.6), and epilepsy due to congenital neurological deficits (SMR 25; 95% CI = 5.1, 73.1) had significantly increased long-term mortality rates, whereas patients with idiopathic epilepsy did not (SMR 1.3; 95% CI = 0.9, 1.9). This increase in mortality rate was noted particularly in the first few years after diagnosis. Multivariate Cox regression and time-dependent co-variate analyses were utilized for the first time in a prospective study of mortality in epilepsy. The former showed that patients with generalized tonic-clonic seizures had an increased risk of mortality. The hazard ratio (HR), or risk of mortality in a particular group with a particular risk factor compared to another group without that particular risk factor, was 6.2 (95% CI = 1.4, 27.7; p = 0.049). Cerebrovascular disease (HR 2.4; 95% CI = 1.7, 3.4; p < 0.0001), central nervous system tumor (HR 12.0; 95% CI = 7.9, 18.2; p < 0.0001), alcohol (HR 2.9; 95% CI = 1.5, 5.7; p = 0.004), and congenital neurological deficits (HR 10.9; 95% CI = 3.2, 36.1; p = 0.003) as causes for epilepsy and older age at index seizure (HR 1.9; 95% CI = 1.7,2.0; p < 0.0001) were also associated with significantly increased mortality rates. These hazard ratios suggest that epilepsy due to congenital neurological deficits may carry almost the same risk of mortality as epilepsy due to central nervous system tumors and that epileptic seizures subsequent to alcohol abuse may carry almost the same risk of mortality as epilepsy due to cerebrovascular disease. The occurrence of one or more seizures before the index seizure (the seizure that led to the diagnosis of epilepsy and enrolment in the study) was associated with a significantly reduced mortality rate (HR 0.57; 95% CI = 0.42, 0.76; p = 0.00001). Time-dependent co-variate analysis was used to examine the influence of ongoing factors, such as seizure recurrence, remission, and antiepileptic drug use, on mortality rates in the cohort. Seizure recurrence (HR 1.30; 95% CI = 0.84, 2.01) and antiepileptic drug treatment (HR 0.97; 95% CI = 0.67, 1.38) did not influence mortality rate. There were only 5 epilepsy-related deaths (1 each of sudden unexpected death in epilepsy, status epilepticus, burns, drowning, and cervical fracture), suggesting that death directly due to epileptic seizures is uncommon in a population-based cohort with epilepsy. Ann Neurol 2001;49:336,344 [source] Differences in Long-term Mortality for Different Emergency Department Presenting ComplaintsACADEMIC EMERGENCY MEDICINE, Issue 1 2008Urban Safwenberg MD Abstract Objectives:, To characterize long-term mortality based on previous emergency department (ED) presenting complaints. Methods:, The authors followed, for 10 years, all of the 12,667 nonsurgical patients visiting an ED during 1995/1996. Differences in standardized mortality ratio (SMR) depending on presenting complaints were then investigated. Results:, During follow-up, 5,324 deaths occurred (mortality rate 6.6 per 100 person-years at risk), giving a SMR of 1.33 (95% CI = 1.30 to 1.37, p < 0.001) when compared with the expected mortality in the catchment area. Different presenting complaints were associated with different long-term mortality rates, independent of age and gender (p < 0.0001). The subjects with seizures had the highest SMR (2.62, 95% CI = 2.13 to 3.22) followed by intoxications (2.51, 95% CI = 2.11 to 2.98), asthmalike symptoms (1.84, 95% CI = 1.65 to 2.06), and hyperglycemia (1.67, 95% CI = 1.42 to 1.95). The largest complaint group, chest pain, had a 20% higher mortality rate than the background population (95% CI = 1.13 to 1.26). Patients with a discharge diagnosis of myocardial infarction, but without chest pain as the presenting complaint, had an increased long-term mortality (hazard ratio [HR] 1.70, 95% CI = 1.15 to 2.42) compared to the group with chest pain. In contrast, stroke patients without strokelike symptoms had a reduced mortality (HR 0.74, 95% CI = 0.65 to 0.84) compared to patients with strokelike symptoms. Conclusions:, Long-term age- and gender-adjusted mortality is the highest with seizures out of 33 presenting complaints and differs markedly between different ED admission complaints. Furthermore, depending on the admission complaint, long-term mortality differs within the same discharge diagnosis. Hence, the presenting complaint adds unique information to the discharge diagnosis regarding long-term mortality in nonsurgical patients. [source] | ||||||||||
