A 54-year-old female with chest pain waking her at night presents with diffuse crackles and a BP of 192/94. What is the most likely diagnosis?

Left-sided heart failure with pulmonary edema explains the findings. Diffuse crackles reflect fluid accumulation in the lungs from increased hydrostatic pressure as the failing left ventricle backs up into the pulmonary circulation. The nocturnal chest symptoms fit paroxysmal nocturnal dyspnea, which happens when lying flat increases venous return and worsens pulmonary edema, waking the patient. The very high blood pressure can accompany hypertensive heart disease or acute decompensation, contributing to this picture. Pulmonary embolism would more often present with sudden, sharp pleuritic chest pain and signs related to ventilation-perfusion mismatch rather than diffuse lung crackles from edema. Myocardial infarction can cause chest pain, but the prominent diffuse crackles point toward fluid overload from heart failure rather than an acute ischemic chest pain alone. Aortic dissection typically presents with abrupt, severe tearing chest pain and often a BP difference between arms, not diffuse lung crackles.
