Chest pain, hypotension and decrease of consciousness are symptoms of inferior myocardial infarction, according to the National Institutes of Health. Additional symptoms of myocardial infarction include cold sweats, sudden dizziness, and aching sensations that radiate to the arms, jaw, back or neck, states Mayo Clinic.
Myocardial infarction is another term for heart attack. Not everyone who suffers myocardial infarction experiences severe symptoms, and some heart attack victims experience no symptoms at all. Recurrent chest pains, or angina, generally occur days or weeks before myocardial infarction, according to Mayo Clinic.
Inferior myocardial infarction is generally regarded as lower risk than myocardial infarction involving the anterior wall of the heart, states the National Institutes of Health.
