Smoking is an important modifiable cardiovascular risk factor and is frequently observed among patients with acute coronary syndrome (ACS). However, the distribution of smoking status across ACS subtypes may vary according to population and clinical setting. Objective: This study aimed to describe smoking status among patients with ACS admitted to an intensive care unit (ICU) and to describe its distribution across ACS subtypes. Methods: A descriptive observational study with a cross-sectional design was conducted among 57 patients diagnosed with ACS and admitted to the ICU of RSI Jemursari, Surabaya, from January 2023 to December 2024. Smoking status was classified as active smoker or non-smoker based on the patient's status at admission. Data were analyzed descriptively using frequencies and percentages, including cross-tabulation of smoking status according to ACS subtype. Results: Of the 57 patients, 22 (38.6%) were active smokers and 35 (61.4%) were non-smokers. The most common ACS subtype was unstable angina pectoris (UAP), accounting for 35 patients (61.4%), followed by non-ST-elevation myocardial infarction (NSTEMI) in 18 patients (31.6%) and ST-elevation myocardial infarction (STEMI) in 4 patients (7.0%). Active smoking was documented in 14 (40.0%) patients with UAP and 8 (44.4%) patients with NSTEMI, whereas none of the patients with STEMI were active smokers. Conclusion: Active smoking was documented in 38.6% of ACS patients admitted to the ICU and was observed primarily among patients with UAP and NSTEMI. Given the descriptive design and the small number of STEMI cases, these findings should not be interpreted as evidence of an association between smoking status and ACS subtype. Nevertheless, documenting smoking status and providing smoking cessation support remain important components of comprehensive cardiovascular care.
