Prospective Validation Of Heart Score For Suspected Acute Coronary Syndrome Patients

Area of Science:

• Cardiology
• Emergency Medicine
• Clinical Risk Stratification

Background:

• The HEART score is a validated tool for assessing patients with suspected acute coronary syndrome (ACS).
• Limited data exists on the HEART score's prognostic utility in specific populations.
• This study aimed to assess the HEART score's predictive value for major adverse cardiac events (MACE) in emergency department patients presenting with chest pain.

Purpose of the Study:

• To evaluate the prognostic accuracy of the HEART score in predicting 6-week MACE.
• To determine the HEART score's utility in risk-stratifying patients with suspected ACS.
• To inform clinical decision-making regarding the discharge of low-risk chest pain patients.

Main Methods:

• Prospective observational study of 281 adult patients presenting with chest pain and suspected ACS.
• Exclusion of patients with a definite ACS diagnosis and those with a HEART score of 7 or higher.
• Calculation of HEART scores and observation of MACE over a 6-week follow-up period.

Main Results:

• The mean HEART score was 4.27 ± 1.06, with 70.8% of patients in the moderate-risk category (score 4-6).
• The HEART score demonstrated strong predictive power for 6-week MACE, with an area under the curve of 0.874.
• No MACE were observed in the low-risk group (HEART score 0-3), compared to a 31.7% MACE rate in the moderate-risk group.

Conclusions:

• The HEART score is a valuable tool for discriminating between patients at low and high risk of MACE within 6 weeks.
• Patients with a HEART score of 0-3 have a very low risk of MACE and may be safely discharged from the emergency department with appropriate follow-up.
• The HEART score can help optimize resource utilization in the emergency department by identifying patients who do not require extensive cardiac workup.
