Both alcohol and cocaine cause hypertension. Excessive ingestion of alcohol can cause a patient to exacerbate his preexisting hypertension, or it can induce hypertension. And cocaine produces devastating effects on blood pressure by increasing the release of norepinephrine, a powerful vasopressor produced by the body in response to hypotension and stress. This can result in acute hypertension, tachycardia, tremor, and seizures as well as coronary artery vasoconstriction from a CVA or Ml.
Many poisons can elevate blood pressure and cause hypertension. Some common poisons include cyanide, phencyclidine, and black widow spider venom. Treatment varies depending on the poison, and it usually relieves the poison-induced hypertension.
Pregnancy-induced hypertension can threaten the lives of both the mother and infant. It causes elevated blood pressure, proteinuria, and edema and may lead to abnormalities in the mother’s coagulation system and liver function. The only treatment for pregnancy-induced hypertension is delivery of the infant.
For some patients, even mild stress can cause a rise in blood pressure. In response to a stressful event, the patient perceives a stressor, and his body initiates a fight-or-flight reaction. Physical signs and symptoms of stress-induced hypertension include decreased gastrointestinal motility, pupil dilation, and increased perspiration, all of which result from sympathetic nervous system stimulation that causes increased blood pressure and increased heart and respiratory rates.
With the white-coat phenomenon, a patient has elevated blood pressure readings in his physician’s office or the hospital but normal readings elsewhere. To determine if a patient has true hypertension, a physician may order repeated measurements over time or ambulatory measurements.
In postoperative patients, stress-related hypertension commonly results from sympathetic stimulation caused by pain, bladder distention, hypothermia, or respiratory compromise.
Sleep apnea can contribute to the development of hypertension. During apnea, the tongue and soft palate relax and fall back, obstructing the airway either partially or completely. As a result, the patient can’t breathe. His oxygen levels fall, and carbon dioxide levels rise, resulting in acidosis and vasoconstriction of the pulmonary arterioles. Eventually, the patient partially awakens, gasps, and reopens his airway. Episodes of apnea may last from 15 to 90 seconds and occur repeatedly during the night.
Diseases Causing Vasculitis
Scleroderma, polyarteritis nodosa, lupus erythematosus, rheumatoid arthritis, and nonspecific arthritis may cause vasculitis in some patients. About one-half of these patients subsequently develop hypertension because of the effect the diseases have on the arterioles and major arteries
