Explanation
A 45-year-old man developed constricting retrosternal pain that occurs during walks at the distance of 200 m. Objectively, heart rate is 80/min., BP is 160/90 mm Hg During cardiopulmonary exercise test at 50 W there is a depression of S-T segment by 3 mm below the isoline in V3-V4. What is the provisional diagnosis?C. Alcoholic myocardiodystrophy → Not indicatedE. Somatoform autonomic dysfunction, hypertension type → Not indicatedCanadian Cardiovascular Society grading scale is used for classification of angina severity, as follows: Class I – Angina only during strenuous or prolonged physical activity Class II – Slight limitation, with angina only during vigorous physical activity Class III – Symptoms with everyday living activities, i.e., moderate limitation Class IV – Inability to perform any activity without angina or angina at rest, i.e., severe limitation
