What is the clinical evidence from this study?

Study design: Observational. Population: Sudden death due to coronary heart disease (n=138). Primary outcome: Potential to be aided by mobile coronary care units.

What question did this study set out to answer?

Key result

Sudden death due to coronary heart disease in 138 nonhospitalized patients occurred predominantly at home (75%), with no more than 22% potentially aidable by mobile coronary care units.

Key Points

To examine the circumstances and timing of sudden coronary heart disease deaths outside hospitals to evaluate the potential lifesaving utility of mobile coronary care units.
Analyzed 138 nonhospitalized patients aged 35 to 75 who died suddenly of coronary heart disease over a one-year period in Montgomery County, Maryland.
Assessed symptom onset, location of collapse, presence of witnesses, prior cardiac history, and elapsed time before dispatching emergency medical aid.
Premonitory symptoms occurred in 65% of cases (chest pain in only 22%), with 75% of deaths occurring at home and 36% (50/138) occurring unwitnessed.
A history of symptomatic heart disease was present in 57% of patients and correlated with faster collapse, leaving at most 22% of victims reachable in time for mobile coronary care units to intervene.

Type

Observational (n=138)

Multicenter

Structured PICO

Population

138 nonhospitalized patients between the ages of 35 to 75 who experienced sudden death due to coronary heart disease in southeastern Montgomery County, Maryland.

Outcome

Circumstances of sudden death (location, witnessed status, premonitory symptoms) and potential benefit from mobile coronary care units

Most sudden cardiac deaths occur at home and are often unwitnessed, limiting the potential impact of mobile coronary care units to a minority of cases.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Mobile coronary care units reach few sudden deaths; leaves open prevention strategies targeting home settings.
