Beyond Platelet Indices, WBC-to-MPV Ratio in Myocardial Infarction With Non-Obstructive Coronary Arteries (MINOCA) Correlate With Short-Term Rather Than In-Hospital Outcomes

Inclusion Criteria: * Age ≥18 years old. * Both sexes. * Patients with acute myocardial infarction (AMI). Myocardial infarction with nonobstructive coronary arteries (MINOCA) is diagnosed if a patient fulfilled the AMI criteria in the absence of obstructive coronary arteries (type I: \<50% stenosis; or type II: no stenosis) as recommended by the recent American Heart Association statement that introduces an updated definition incorporating the 4th universal MI definition, which by agreement excludes Takotsubo syndrome and myocarditis from the eventual diagnosis of MINOCA. Exclusion Criteria: * Previous history of MI or coronary revascularization (PCI or bypass surgery) with acute/chronic infection. * Autoimmune diseases. * Systemic inflammatory disease. * Patients on treatment therapy which critically affects inflammatory cell count. * Patients with malignancy. * Chronic kidney disease. * Severe liver disease. * Severe anemia. * Fever (\>38°C).
