In his article “High-Risk Hypertensive Patients: How to Optimize Therapy UsingACE Inhibitors and ARBs” (CONSULTANT, October 2003, page 1390), Dr JanBasile recommends angiotensin-converting enzyme (ACE) inhibitors for patientswith type 1 diabetes with or without hypertension, whether or not nephropathyis present.

A 45-year-old woman is admitted for evaluation of intermittentmidsternal chest pain that began 48 hours earlier.The pain is intense and radiates down both arms to theelbows; it has been accompanied by several episodes ofnausea and diaphoresis. She denies classic angina pectorisbut reports that she has experienced episodes of chestdiscomfort that is similar to her current pain-but muchless severe and without radiation-for about 3 months.She has no history of dyspnea on exertion, orthopnea, orparoxysmal nocturnal dyspnea.

If you are a long-time reader of this journal, you may rememberthe photographs of authors that once gracedthe cover of every issue of Consultant. The May 1979issue of Consultant featured the picture of Donald Vidtyou see here; for that issue, Dr Vidt wrote “FiveMajor Vasodilators: How They Work” and advised readersabout the cardiovascular and renal hemodynamics ofhydralazine, prazosin, diazoxide, nitroprusside, and (atthat time the investigational agent) minoxidil. A quarter of a century later,Dr Vidt is still writing on the treatment of hypertension for readers of thisjournal-and it is with real pleasure that we introduce him here as a memberof our editorial board.

A 57-year-old African American man comes to your office because he isconcerned about his blood pressure (BP). When it was measured at a healthfair a month earlier, it was 157/96 mm Hg; a week later at a clinic it was162/97 mm Hg. Now his resting BP is 166/101 mm Hg.

Over the past 8 years, fragile vesicles,painful ruptured bullae, and erosionshave developed on the sun-exposed skinof a 57-year-old man. Some of the vesicleserupt at sites of minor trauma; othersarise spontaneously. A corticosteroidcream prescribed by another practitionerfor presumed atopic dermatitisfailed to clear the lesions.

Q:How frequently does hypertension occur in association withobstructive sleep apnea (OSA), and how is OSA best treated?

Heart failure statistics are daunting:550,000 new cases each year, a 1-yearmortality rate of nearly 20%, and annualdirect and indirect costs that total $24.3billion.1 The diverse etiology of heartfailure and the complex, progressivecourse of the disease can make treatmentdecisions daunting as well.

A 56-year-old African American woman complains of malaise, nausea, and vomitingof several weeks’ duration. In addition, urinary output is reduced, and shehas mild dyspnea. She denies abdominal pain, diarrhea, constipation, and bonepain; however, she has had a mild but persistent backache for several months.

The pain began 3 hours earlier and is associated with diaphoresisand dyspnea. Examination results are unremarkable, except for diaphoresis.A 12-lead ECG reveals normal sinus rhythm with large R waves and horizontalST-segment depression in leads V1 through V3. The patient is given nitroglycerin,aspirin, heparin, morphine, and a &#946-blocker for noninfarction acutecardiac ischemia and transferred to the local emergency department (ED).

A 58-year-old man complains ofintermittent headaches that beganabout 2 months earlier and have recentlyincreased in severity. Theheadaches occur at various times ofthe day and improve slightly whenhe sits. He denies trauma, fever, photophobia,and other neurologicsymptoms.

The incidence of hypertension, diabetes, certain types ofcancer, and other chronic diseases is disproportionatelyhigher in African Americans than in white Americans. Thestatistics presented in the Table illustrate the magnitudeof this disparity. For other diseases, such as breast cancer,the incidence is lower but mortality is higher in AfricanAmericans.

Twenty-four-hour ambulatory blood pressure (BP) monitoringis a more accurate predictor of stroke and myocardialinfarction than office BP measurement, according tothe results of the recent Office Versus Ambulatory BloodPressure Study. This prospective trial followed 1963 patientswith treated hypertension for 5 years.

An 84-year-old woman with hypertension and type 2 diabetes mellitus isbrought to the emergency department (ED) after an episode of nearsyncope.When emergency medical service personnel initially assessed her,blood pressure was 96/60 mm Hg and heart rate was “slow”; however, shehad no symptoms.

A 74-year-old man with a history ofatrial fibrillation presents to hisprimary care physician with dyspneaof 4 days’ duration. The dyspnea developedwhile he was walking as partof his recovery from back surgery forspinal stenosis 1 month earlier. Hebecame progressively short of breathand was unable to carry out his exerciseprogram.
