Cardiovascular Effects of Systemic Diseases

Chapter 13 Cardiovascular Effects of Systemic Diseases



Francis W.K. Smith, Jr., Donald P. Schrope, Carl D. Sammarco



INTRODUCTION


Many systemic diseases are capable of profoundly affecting cardiovascular structure and function (Box 13-1). The veterinarian may detect cardiovascular abnormalities as the predominant clinical sign or systemic disease manifestations may overshadow cardiac abnormalities. Although cardiovascular manifestations may sometimes be of no clinical significance, at other times they may constitute the major medical concern. Detection of cardiovascular involvement may be based on clinical signs, radiographic changes, electrocardiographic (ECG) or echocardiographic abnormalities, or laboratory findings. Emphasis in this chapter is given to diseases having the greatest cardiovascular effects or incidence in practice. The focus of discussion is the cardiovascular effects and their treatment.

• ECG changes vary with the magnitude of the hyperkalemia and are aggravated by hyponatremia, hypocalcemia, and acidosis. The following ECG findings are seen with experimentally induced hyperkalemia (Figure 13-1):
