Mortality may be declining in people with heart disease, but more and more are experiencing a long lead-up to clinical disease, without an appropriate intervention. The toxicity of our environmental, social, and cultural worlds creates pathophysiologic disturbances such as obesity, diabetes, and, in some cases, heart disease. In Vascular Biology for the Clinician, Mark Houston, MD, MS, MSc, along with Joseph Lamb, MD, and Anita Hays, PhD, suggests to doctors ways to diagnosis cardiovascular diseases at an earlier stage and treat their underlying causes. Houston is board-certified in hypertension, internal medicine, and anti-aging medicine. He runs an active practice and has authored nineteen books and 172 articles on hypertension and cardiovascular diseases and served as editor or reviewer for medical journals.
