Why the study?
Does nonobstructive acute coronary syndrome have different clinical outcomes compared to critical obstructive ACS in patients with unstable angina or NSTEMI, and how does khat chewing affect these outcomes?
Does nonobstructive acute coronary syndrome have different clinical outcomes compared to critical obstructive ACS in patients with unstable angina or NSTEMI, and how does khat chewing affect these outcomes?
Nonobstructive ACS has a better overall prognosis than obstructive ACS, but patients with 20-50% stenosis, often associated with heavy khat chewing, face significantly higher risks of adverse cardiac events than those with minimal or no atherosclerosis.
May support differential prognosis in nonobstructive ACS; leaves open khat chewing's role in moderate-stenosis outcomes.
