Clinical characteristics, background illnesses and in-hospital mortality rates of patients who has a temporary pacemaker implanted

Background: Among patients hospitalized for acute ischemic stroke, abnormal serum troponins are associated with higher risk of short-term mortality. However, most findings have been reported from European hospitals. Whether troponin elevation after stroke is independently associated with death among a more heterogeneous US population remains unclear. Furthermore, only a few studies have evaluated the association between the magnitude of troponin elevation and subsequent mortality, patterns of dynamic troponin changes over time, or whether troponin elevation is related to specific causes of death. Methods: Using data collected in the American Heart Association's ‘Get With The Guidelines' stroke registry between 2008 and 2012 at a tertiary care US hospital, we used logistic regression to evaluate the independent relationship between troponin elevation and mortality after adjusting for demographic and clinical characteristics. We then assessed whether the magnitude of troponin elevation was related to in-hospital mortality by calculating mortality rates according to tertiles of peak troponin levels. Dynamic troponin changes over time were evaluated as well. To better understand whether troponin elevation identified patients most likely to die due to a specific cause of death, investigators blinded from troponin values reviewed all in-hospital deaths, and the association between troponin elevation and mortality was evaluated among patients with cardiac, neurologic, or other causes of death. Results: Of 1,145 ischemic stroke patients, 199 (17%) had elevated troponin levels. Troponin-positive patients had more cardiovascular risk factors, more intensive medical therapy, and greater use of cardiac procedures. These individuals had higher in-hospital mortality rates than troponin-negative patients (27 vs. 8%, p < 0.001), and this association persisted after adjustment for 13 clinical and management variables (OR 4.28, 95% CI 2.40-7.63). Any troponin elevation was associated with higher mortality, even at very low peak troponin levels (mortality rates 24-29% across tertiles of troponin). Patients with persistently rising troponin levels had fewer anticoagulant and antiatherosclerotic therapies, with markedly worse outcomes. Furthermore, troponin-positive patients had higher rates of all categories of death: neurologic (17 vs. 7%), cardiac (5 vs. <1%), and other causes of death (5 vs. <1%; p < 0.001 for all comparisons). Conclusions: Ischemic stroke patients with abnormal troponin levels are at higher risk of in-hospital death, even after accounting for demographic and clinical characteristics, and any degree of troponin elevation identifies this higher level of risk. Troponins that continue to rise during the hospitalization identify stroke patients at markedly higher risk of mortality, and both neurologic and non-neurologically mediated mortality rates are higher when troponin is elevated.

The Impact

Abstract Background Ethnic disparities have been reported in cardiovascular disease. However, ethnic disparities in takotsubo syndrome (TTS) remain elusive. This study assessed differences in clinical characteristics between Japanese and European TTS patients and determined the impact of ethnicity on in-hospital outcomes. Methods TTS patients in Japan were enrolled from 10 hospitals and TTS patients in Europe were enrolled from 32 hospitals participating in the International Takotsubo Registry. Clinical characteristics and in-hospital outcomes were compared between Japanese and European patients. Results A total of 503 Japanese and 1670 European patients were included. Japanese patients were older (72.6 ± 11.4 years vs. 68.0 ± 12.0 years; p < 0.001) and more likely to be male (18.5 vs. 8.4%; p < 0.001) than European TTS patients. Physical triggering factors were more common (45.5 vs. 32.0%; p < 0.001), and emotional triggers less common (17.5 vs. 31.5%; p < 0.001), in Japanese patients than in European patients. Japanese patients were more likely to experience cardiogenic shock during the acute phase (15.5 vs. 9.0%; p < 0.001) and had a higher in-hospital mortality (8.2 vs. 3.2%; p < 0.001). However, ethnicity itself did not appear to have an impact on in-hospital mortality. Machine learning approach revealed that the presence of physical stressors was the most important prognostic factor in both Japanese and European TTS patients. Conclusion Differences in clinical characteristics and in-hospital outcomes between Japanese and European TTS patients exist. Ethnicity does not impact the outcome in TTS patients. The worse in-hospital outcome in Japanese patients, is mainly driven by the higher prevalence of physical triggers.

Abstract Background Cardiac troponin (cTn) is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). Octogenarians who presented cTn positive AMI are not usually recruited in clinical trials. Therefore, their clinical characteristics and prognosis are rarely investigated. Objective To study the characteristics and prognosis in octogenarians who presented cTn positive AMI. Methods and results The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective and multicenter registry. A total of 3,283 consecutive AMI patients who were diagnosed by cTn-based criteria were included. The patients were divided into non-octogenarians (n=2,593) and octogenarians (n=690). Compared with non- octogenarians, octogenarians showed significantly lower incidence of diabetes mellitus (37.6% and 31.9%, p=0.006) and dyslipidemia (53.6% and 45.6%, p<0.001), and significantly higher incidence of hypertension (64.1% and 75.3%, p<0.001) and chronic kidney disease (38.7% and 68.7%, p<0.001). Octogenarians showed significantly longer onset to door time (p<0.001) and longer door to device time (p<0.001). Though, compared with non-octogenarians, octogenarians showed lower peak CK (2,506 and 1,926, p<0.001), LVEF was significantly lower in octogenarians (54.6% and 52.6%, p=0.005). The presentation of AMI was different between the two group. The incidence of ST-segment elevation MI (STEMI) was 70.7% in non-octogenarians and 62.0% in octogenarians. Non-STEMI with CK elevation and without CK elevation were 16.2% and 13.1% in non- octogenarians, and 20.9% and 17.1% in octogenarians. In-hospital mortality was higher in octogenarians (4.7% and 13.2%, P<0.001). Especially, octogenarians with STEMI and non-STEMI with CK elevation showed the highest in-hospital mortality. And octogenarians without CK elevation showed similar in hospital mortality with non-octogenarians with STEMI (Figure). Conclusions J-MINUET showed the poor prognosis of octogenarians who were diagnosed as AMI based on cTn. Acknowledgement/Funding None

Abstract Background Severe aortic stenosis patients suffer frequent heart failure decompensations events often requiring hospitalization. In extreme situations patients can be found with pulmonary edema and cardiogenic shock, unresponsive to medical treatment. Urgent trans-catheter aortic valve implantation (TAVI) has emerged as a treatment option for these high-risk patients. Methods We investigated 3,599 patients undergoing TAVI. Subjects were divided into two groups based on procedure urgency: patients who were electively hospitalized for the procedure (N=3,448) and those who had an urgent TAVI (N=151). Peri-procedural complications were documented according to the VARC-2 criteria. In hospital and 1-year mortality rates were prospectively documented. Results Mean age of the study population was 82±7, of whom 52% were female. Peri-procedural complication rates was significantly higher among patients with an urgent indication for TAVI compared to those having an elective procedure: valve malposition 3.6% vs. 0.6% (p-value=0.023), valve migration 3.2% vs. 0.9% (p-value=0.016), post procedure myocardial infarction 3.7% vs. 0.3% (p-value=0.004), and stage 3 acute kidney injury 2.6% vs. 0.5%, (p-value=0.02). Univariate analysis found that patients with urgent indication for TAVI had significantly higher in hospital mortality (5.8% vs. 1.4%, p-value<0.001). similarly, multivariate analysis adjusted for age, gender and cardio-vascular risk factors found that patients with urgent indication had more than 5-folds increased risk of in-hospital mortality (OR 5.94, 95% CI 2.28–15.43, p-value<0.001). Kaplan-Meier's survival analysis showed that patients undergoing urgent TAVI had higher 1-year mortality rates compared to patients undergoing an elective TAVI procedure (p-value log-rank<0.001, Figure). Multivariate analysis found they had more than 2-folds increased risk of mortality at 1-year (HR 2.27, 95% CI 1.53–3.38, p<0.001 compared to those having an elective procedure. Conclusions Patients with urgent indication for TAVI have higher in-hospital mortality and higher peri-procedural complication rates. However, if these patients survive the index hospitalization, they enjoy good prognosis. Kaplan-Meier's survival analysis Funding Acknowledgement Type of funding source: None

Patients With Diabetes

In this study, demographic characteristics, risk factors, stroke subtypes and outcome were compared in 2532 patients with and without diabetes hospitalized for first-ever stroke. Diabetes was present in 471 (18.6%) of the patients. Patients with diabetes presented more frequently with ischaemic stroke (92.1% versus 71.3%), especially lacunar infarction (41.2% versus 35.2%), compared with non-diabetics. Cerebral haemorrhage was less frequent in diabetics than non-diabetics (4.2% versus 18.1%). In-hospital mortality rates from ischaemic stroke were similar in the two groups (18.2% in diabetics and 16.9% in non-diabetics). Predictors of in-hospital mortality in diabetic patients included decreased consciousness, congestive heart failure and atrial fibrillation. In conclusion, stroke in diabetic patients was different to stroke in non-diabetic patients: in diabetics the frequency of cerebral haemorrhage was lower and the rate of lacunar infarct syndrome was higher, but in-hospital mortality from ischaemic stroke was not increased. Clinical factors evident at the onset of stroke have a major influence on in-hospital mortality and may help clinicians provide a more accurate prognosis.

Shared Risk

Background: COPD recently overtook stroke as the third leading cause of death in the United States. Intriguingly, smoking is an important shared risk factor for both stroke and COPD; COPD patients have baseline cerebral hypoxia and hypercapnia that could potentially exacerbate vascular brain injury; and stroke patients with COPD are at higher risk of aspiration than those without COPD. Yet, relatively little is known about the prevalence of COPD among stroke patients or its impact on outcomes after an index stroke. Objective: To assess prevalence of COPD among hospitalized stroke patients in a nationally representative sample and examine the effect of COPD with risk of dying in the hospital after a stroke. Methods: Data were obtained for patients, 18 years and older, from the National Inpatient Sample from 2004-2009 (n=48,087,002). Primary discharge diagnoses of stroke were identified using ICD-9 diagnosis codes 430-432 and 433-436, of which a subset with comorbid COPD were defined with secondary ICD-9 diagnoses codes 490-492, 494, and 496. In-hospital mortality rates were calculated, and independent associations of COPD with in-hospital mortality following stroke were evaluated with logistic regression. All analysis were survey-weighted. Results: 11.71% (95% CI 11.48-11.94) of all adult patients hospitalized for stroke had COPD. The crude and age-adjusted in-hospital mortality rates for these patients were 6.33% (95% CI 6.14-6.53) and 5.99% (95% CI 4.05-7.94), respectively. COPD was independently and modestly associated with overall stroke mortality (OR 1.03, 95% CI 1.01-1.06; p=0.02). However, when analyzed by subtype, greater risks of mortality were seen in those with intracerebral hemorrhage (OR 1.12, 95% CI 1.03-1.20; p<0.01), and ischemic stroke (OR 1.08; 95% CI 1.03-1.13, p<0.01), but not subarachnoid hemorrhage (OR 0.98, 95% CI 0.85-1.13; p=0.78). There were no statistically significant interactions between COPD and age, gender, or race. Conclusion: 12% of hospitalized stroke patients have COPD. Presence of COPD is independently associated with higher odds of dying during ischemic stroke hospitalization. Prospective studies are needed to identify any modifiable risk factors contributing to this deleterious relationship.
