Key result
Acute cardiac complications after subarachnoid hemorrhage are linked to ~53% higher 3-month mortality.
Why the study?
Cardiac complications frequently occur after subarachnoid hemorrhage and their impact on long-term mortality and cardiovascular events was unclear.
Do acute cardiac complications increase the risk of long-term mortality and cardiovascular events in patients with subarachnoid hemorrhage?
Population
455 patients with verified SAH admitted to a Neuro intensive care unit
Comparison
Presence vs absence of acute cardiac complications after SAH
Design
Cohort study

May prompt closer short-term cardiac monitoring after SAH; leaves open whether targeted interventions alter outcomes.

Do acute cardiac complications increase the risk of long-term mortality and cardiovascular events in patients with subarachnoid hemorrhage?
Hazard Ratio: 1.53 (95% CI 1.02–2.29)
p-value: p=0.040
Acute cardiac complications after subarachnoid hemorrhage are associated with increased short-term mortality and long-term cardiovascular and cerebrovascular events, highlighting the need for appropriate follow-up.
Norberg et al. (2018) conducted a cohort in Subarachnoid hemorrhage (n=455). Acute cardiac complications (e.g., ST-T abnormalities) vs. Absence of acute cardiac complications was evaluated on Mortality (HR 1.53, 95% CI 1.02-2.29, p=0.040). Acute cardiac complications after subarachnoid hemorrhage, including ST-T abnormalities (HR 1.53), were independently associated with an increased risk of death during the first 3 months.
