Prior to his MI, he was not on medications. He is not a smoker and is not diabetic. During his hospitalization, he was noted to have persistently elevated blood pressure readings. He had asthma as a child, but has not had any recent wheezing episodes . While in the hospital, he was started on oral metoprolol.

Clinical Case 6

  1. 1.  A 70-Year-old man is seen in follow-up at your office after he has been hospitalized for a myocardial infarction. He underwent successful angioplasty and is currently asymptomatic. Prior to his MI, he was not on medications. He is not a smoker and is not diabetic. During his hospitalization, he was noted to have persistently elevated blood pressure readings. He had asthma as a child, but has not had any recent wheezing episodes . While in the hospital, he was started on oral metoprolol.
  2. 2. Questions 1. Metoprolol is selective for which adrenoceptor? 2. What effects do agents such as metoprolol have on the cardiovascular system? 3. In which organ is metoprolol primarily metabolized? 4. Why must beta adrenergic antagonists be used with caution in asthmatics?
  3. 3. Summary  A 70-year-old hypertensive man with a childhood history of asthma had a recent myocardial infarction and is prescribed metoprolol
  4. 4. Adrenoceptor selectively antagonized by metaprolol Beta 1
  5. 5. Effect of beta adrenoceptor antagonists on the cardiovascular system  Reduction of sympathetic-stimulated increases in heart rate, contractility and cardiac output  Lower BP as a result of effects on heart, renin- angiotensin system, and CNS  Increased atrioventricular (AV) conduction time and refractoriness.
  6. 6. Organ in which metoprolol is metabolized Liver
  7. 7. Reason for caution in use in asthhmatics  Blockade of beta 2 adrenoceptor in bronchial smooth muscle may cause increased airway resistance and bronchospasm
