The patient provided details regarding their chief complaint that included a sudden onset of severe chest pain which was described as sharp and radiating to their left arm. Additionally, they reported feeling shortness of breath, light-headedness and nausea which further increased with exertion. Upon physical examination the patient had a weak radial pulse and pale skin colouration which along with other observations suggested cardiac-related symptoms.

Based on these reports along with vital signs obtained during the assessment, it appears likely that the patient is experiencing a heart attack. Other possible differential diagnoses include pericarditis or angina; however given their age and medical history (no significant conditions) it is more likely to be an acute coronary event such as a myocardial infarction or unstable angina.
