Recall that blood pressure = cardiac output x total peripheral resistance. When the cardiac output decreases, the vasculature increases its tone to increase the blood pressure. This increase in vascular tone increases the peripheral resistance. High-output heart failure Cardiogenic shock is defined as low-output failure. Tachycardia Patients with cardiogenic shock often have tachycardia to compensate for the low cardiac output. Strong radial pulse Patients with cardiogenic shock usually have a non-palpable or decreased pulse due to the development of tachyarrhythmias. Polyuria Patients with cardiogenic shock often have oliguria due to decreased perfusion to the kidneys. Pathophysiology An 82-year-old man is brought to the emergency department with severe shortness of breath, sweating, and altered state of consciousness. Past medical history is significant for prior myocardial infarction with ischemic heart failure. Physical examination is remarkable for cold extremities. After initial assessment, the patient is diagnosed with cardiogenic shock. Which of the following additional findings is consistent with the patient's condition?
