“…Patients with MI experience chest pain, pain radiating to the shoulder (location near the heart and its felt beats), and pressure (also a sign of over exertion), and have rapid onset and rapid increases in severity of symptoms (time lines). These elements map to heart and each of them is positively and independently associated with more rapid care seeking [27]. The location of symptoms experienced by patients with CHF, e.g., problems breathing, swollen legs, and the time frames of these symptoms, e.g., chronic, slow changes before catastrophic changes, lack the pattern and rate of change for attribution to the heart [28].…”
