A 74-year-old man comes to the GP because of a 4-month history of worsening exercise tolerance and shortness of breath with exertion. His vitals are: temperature 98.6F, HR 90, RR 20, BP 124/80. Auscultation of the lung fields shows bibasilar crackles. An S3 gallop and 2/6 holosystolic murmur are auscultated on cardiac exam. There is no radiation of the murmur to the axilla. The point of maximal impulse is palpated at the 6th intercostal space in the anterior axillary line. Which of the following is most likely to be seen in this patient?
↑ Systemic vascular resistance; ↑ Pulmonary capillary wedge pressure; ↔ Ejection fraction
↑ Systemic vascular resistance; ↔ Pulmonary capillary wedge pressure; ↓ Ejection fraction
↑ Systemic vascular resistance; ↑ Pulmonary capillary wedge pressure; ↓ Ejection fraction
↓ Systemic vascular resistance; ↑ Pulmonary capillary wedge pressure; ↔ Ejection fraction
