In-Hospital Outcomes of Acute Ischemic Stroke in Patients With Hypertrophic Cardiomyopathy.

ABSTRACT:

Objective

To investigate the in-hospital outcomes of acute ischemic stroke in patients with hypertrophic cardiomyopathy (HCM).

Patients and methods

Using weighted discharge data from the National Inpatient Sample, we identified 5804 nonelective hospitalizations for ischemic stroke in adult patients with HCM between 2011 and 2017. For comparison, 58,179 hospitalizations for ischemic stroke in adult patients without HCM were selected as controls using the simple random sampling method.

Results

Compared with the patients without HCM, those with HCM had a higher prevalence of hyperlipidemia (62.4% vs 57.5%, respectively, P<.001) and chronic heart failure (25.4% vs 13.6%, respectively, P<.001) but a lower prevalence of diabetes (28.2% vs 34.9%, respectively, P<.001) and hypertension (42.9% vs 53.4%, respectively, P<.001). Atrial fibrillation was documented in 45.1% (n=2617) of the patients with HCM. However, only 28.0% (n=733) of these patients had long-term use of anticoagulants. The in-hospital death rate among the patients with HCM was 6.3% (n=368), which was significantly higher than that in the patients without HCM (4.1%, P<.001). Having HCM (odds ratio [OR], 1.35; P<.001), atrial fibrillation (OR, 2.08; P<.001), and chronic heart failure (OR, 1.65; P<.001) were significant predictors of in-hospital death. In patients with HCM who were discharged alive, 50.0% were transferred to skilled nursing facilities compared with 45.3% of those without HCM (P<.001).

Conclusion

The prognosis of acute ischemic stroke is worse in patients with HCM than in those without HCM. These findings emphasize the importance of aggressive treatment of predisposing factors for stroke in patients with HCM, especially atrial fibrillation.

Project description:AimsIt is unclear whether early cardiac rhythm control is beneficial in patients with acute ischemic stroke and paroxysmal atrial fibrillation (PAF). We sought to investigate whether PAF self-termination and in-hospital sinus rhythm (SR) restoration is associated with improved outcome in ischemic stroke patients with PAF, compared to those with sustained atrial fibrillation (AF).MethodsConsecutive patients with first-ever acute stroke and confirmed PAF during hospitalization were followed for up to 10 years after the index stroke or until death. We investigated the association of in-hospital self-terminated PAF and PAF conversion to SR compared to sustained AF with 10-year all-cause mortality, stroke recurrence, and major adverse cardiovascular events (MACE). Cox regression analysis was performed to identify independent predictors of each outcome.ResultsAmong 297 ischemic stroke patients with in-hospital PAF detection, PAF was self-terminated in 87 (29.3%) patients, while 143 (48.1%) patients received antiarrhythmic medication in order to achieve PAF conversion to SR. During a median (Interquartile range, IQR) period of 28 (4-68) months, among patients with self-terminated PAF there were 13.5 deaths, 3.6 stroke recurrences, and 5.3 MACE per 100 patient-year while in patients who underwent medical PAF conversion there were 11.7 deaths, 4.6 stroke recurrences, and 5.8 MACE per 100 patient-year. Patients with sustained AF experienced 23.8 deaths, 8.7 stroke recurrences, and 13.9 MACE per 100 patient-years. In multivariable analysis, compared to patients with sustained AF, PAF self-termination was associated with significantly lower 10 years-risk of death (adjusted hazards ratio (adjHR): HR: 0.63, 95% Confidence interval: 0.40-0.96), stroke recurrence (adjHR: HR: 0.41, 95% CI: 0.19-0.91), and MACE (adjHR: 0.43, 95% CI: 0.23-0.81), while PAF medical conversion to SR was associated with lower 10 years-risk of death (adjHR: 0.65, 95% CI: 0.44-0.97) and MACE (adjHR: 0.56, 95% CI: 0.33-0.95).DiscussionThis study showed that in-hospital PAF self-termination was associated with lower risk of 10-year mortality, stroke recurrence, and MACE, potentially attributed to the lower burden of AF, whereas in-hospital PAF conversion to SR was associated with lower risk of 10-year mortality and MACE.ConclusionEarly restoration of sinus rhythm is associated with improved survival and MACE in patients with acute ischemic stroke and PAF.

Project description:ImportanceAlthough overall stroke incidence and mortality in the United States is improving, little is known about the characteristics and clinical outcomes of acute ischemic stroke in Asian American individuals.ObjectiveTo compare the characteristics, care, and outcomes of Asian American and white patients with acute ischemic stroke.Design, setting, participantsRetrospective analysis of Asian American and white patients admitted with a primary diagnosis of acute ischemic stroke to hospitals participating in the Get With The Guidelines-Stroke (GWTG-Stroke) program between April 1, 2004, and July 31, 2016. The GWTG-Stroke database is a prospectively collected stroke quality improvement registry sponsored by the American Heart Association/American Stroke Association.Main outcomes and measuresMultivariable logistic regression models assessed the association of Asian American race/ethnicity, clinical outcomes, and quality measures.ResultsThe study population of 1 772 299 patients (mean [SD] age, 72.4 [14.2] years; 51.3% female) consisted of 64 337 Asian American patients (3.6%) and 1 707 962 white patients (96.4%) admitted to 2171 GWTG-Stroke hospitals with acute ischemic stroke. After adjustment for patient and hospital variables, Asian American patients were seen with greater stroke severity compared with white patients (National Institutes of Health Stroke Scale [NIHSS] score ≥16) (odds ratio [OR], 1.35; 95% CI, 1.30-1.40; P < .001), manifested higher in-hospital mortality (OR, 1.14; 95% CI, 1.09-1.19; P < .001), had longer length of stay (OR, 1.17; 95% CI, 1.14-1.20; P < .001), and were less likely to ambulate independently at discharge (OR, 0.84; 95% CI, 0.79-0.90; P < .001). Although Asian American patients had fewer intravenous tissue plasminogen activator (IV tPA) administrations than white patients (OR, 0.95; 95% CI, 0.91-0.98; P = .003), they had more symptomatic hemorrhage after tPA (OR, 1.36; 95% CI, 1.20-1.55; P < .001) and overall post-tPA complications (OR, 1.31; 95% CI, 1.18-1.46; P < .001). Asian American patients had better quality measure adherence overall than white patients, including rehabilitation (OR, 1.27; 95% CI, 1.18-1.36; P < .001), door to tPA within 60 minutes (OR, 1.14; 95% CI, 1.06-1.22; P < .001), and intensive statin therapy (OR, 1.14; 95% CI, 1.10-1.18; P < .001). After adjustment for stroke severity, Asian American patients had lower in-hospital mortality than white patients (OR, 0.95; 95% CI, 0.91-0.99; P = .008).Conclusions and relevanceAsian American patients manifested more severe ischemic strokes, were less likely to receive IV tPA, and had worse functional outcomes than white patients. These findings warrant additional research toward improving clinical outcomes for Asian American patients with acute ischemic stroke.
