Syndromes of Concurrent Hypertension, Diastolic Dysfunction, and Pulmonary or Peripheral Edema in Cardio-Oncology:...

Individuals who have ever been diagnosed with cancer are at increased risk for cardiovascular conditions during and after cancer treatment. Especially during cancer treatment, cardiovascular conditions can manifest in many ways, including peripheral or pulmonary edema. Edema can indicate volume overload affecting the heart even without other unequivocal evidence of apparent diastolic or systolic left ventricular dysfunction, particularly at rest. We propose a novel algorithm to streamline the diagnostic evaluation and cardiovascular classification for cancer patients with edema. We initially advise prompt evaluation with a chest X-ray and echocardiogram. We then suggest classification into one of five categories based on the timing of presentation of edema relative to cancer treatment, as well as echocardiography results and the presence or absence of hypertension or lymphatic causes of edema. This classification tool can then be utilized to guide further cardiovascular management suggestions. These concurrent syndromes presenting as edema may indicate the development or aggravation of undiagnosed diastolic dysfunction with or without hypertension, even if transiently present only while on cancer treatment.
