Mortality After Acute Stroke Worsened by Accompanying Acute AF

Mortality After Acute Stroke Worsened by Accompanying Acute AF

The examine coated on this abstract was revealed on as a preprint and has not but been peer-reviewed.

Key Takeaway

Acute atrial fibrillation (AF) is an impartial predictor of severity of neurological deficits from early acute ischemic stroke and a high-probability predictor of demise inside 30 days after such strokes.

Why This Issues

Examine Design

The retrospective examine included sufferers with acute ischemic stroke inside the prior 24 hours; 12-lead electrocardiogram within the emergency division; and hospitalization and therapy on the hospital stroke middle.

The cohort of 706 sufferers admitted to a single middle in Shanghai, China, from December 2019 to December 2021, included 142 with episodes of acute AF and 564 with out such episodes.

Sufferers with acute ischemic stroke and acute AF — together with AF of latest onset, paroxysmal, persistent, or everlasting with signs resembling palpitations or dizziness attributed to speedy ventricular charges — have been recognized.

Neurological deficits have been assessed utilizing the 7-day Nationwide Institutes of Well being Stroke Scale/Rating (NIHSS). Sufferers with a 7-day NIHSS rating of at the least 16 have been thought of to have moderate-to-severe stroke.

Associations between acute AF onset and the severity of early neurological deficits have been assessed and associated to all-cause mortality inside 30 days of the stroke.

Key Outcomes

Sufferers with acute AF have been older than these with out acute AF (80.Three y vs y; P < .001).

Baseline NIHSS scores averaged 16.09 for the stroke sufferers with acute AF and eight.65 for these with out acute AF (P < .001).

Considerably extra sufferers with acute AF than with out acute AF had a 7-day NIHSS rating of at the least 16 (45.1% vs 14.4%; P < .001).

Extra sufferers with than with out acute AF underwent transcatheter thrombectomy (44.4% vs 24.5%; P < .001) or obtained thrombolytic remedy (31.6% vs 19.7%; P = .005).

Sufferers aged 73 years or older confirmed baseline NIHSS rating and acute AF as impartial danger components for early neurological deficits in stroke sufferers admitted to the emergency division.

Mortality at 30 days was considerably larger in sufferers with acute AF than in these with out acute AF (30.3% vs 10.1%; P < .001).

Baseline NHISS had an adjusted odds ratio for 30-day mortality of 1.18 (95% confidence interval [CI], 1.15 – 1.22; P < .001).  

Different impartial predictors included acute AF (1.87 [95% CI, 1.09 – 3.19; P = .022]) and age 73 or older (2.00 [95% CI, 1.18 – 3.37; P = .01]).


The examine was retrospective and did not have entry to some probably related knowledge, resembling length of AF.

The only-center examine with restricted generalizability doesn’t essentially signify the broad inhabitants of stroke sufferers in China or elsewhere.


This examine was supported by the Cardiovascular Multidisciplinary Built-in Analysis Fund and Development of Shanghai Municipal Well being Fee.

The authors report no related monetary relationships.
