By ΝΙΚΟΛΑΟΣ ΦΡΟΥΝΤΖΟΣ

Abstract

FROM THE FOLLOW-UP AT LEAST FOR ONE YEAR OF 96,8% OF THE CASES OF ONE INITIAL COHORT OF 530 SUBJECTS OF BOTH SEXES WITH A WIDE RANGE OF CHEST COMPLAINS AND OR REST REPOLARIZATION CHANGES SUBJECTED TO ONE ECGPHIC STRESS TEST, ARE DRAWNTHE FOLLOWING CONCLUSIONS. 1. AS IT CONCERNS THE EVOLUTION OF SYMPTOMATOLOGY:A) ASYMPTOMATICS 20% (FROM A 6%) INITIALLY. B) SYMPTOMATIC IMPROVEMENT 23,9%,C) UNCHANGED SYMPTOMATOLOGY 40,3%, D) WORSENING OF SYMPTOMS 4,5%, E) NO LETHAL CARDIAC EVENTS 4,3%. 2. MORTALITY TOTAL 2,7% AND CARDIAC 1,7%. 3. OF THE PARAMETERS OF THE INITIAL DATA THE FOLLOWING WERE UNRELATED TO SYMPTOMATIC EVOLUTION A) SEX, B) AGE, C) INITIAL REST REPOLARIZATION CHANGES, D) DURATION OF EXERCISE TESTING, E) SMOKING. 4. INSTEAD THE FOLLOWING PARAMETERS WERE RELATED AND PREDICTIVE OF THE LATE SYMPTOMATIC OUTCOME, A) KIND OF INITIAL COMPLAINS, B) REST HEART RATE, C) POST EXERCISE HEART RATE, D) POST EXERCISE ECGPHIC CHANGES. 5. DRUG CONSUMED DURING THE FOLLOW-UP DO NOT ACCOUNT FOR THE IMPROVEMENT OF SYMPTOMS. 6. THE LETHAL OUTCOME IS ESSENTIALLY PREDICTED ONLY BY LOW POST-EXERCISE HEART RATES. THUS IT CAN SAID THAT SYMPTOMATIC EVOLUTION AND SURVIVAL OF CASES AS THOSE STUDIED HEREIN IS BETTER THAN BELIEVED SO FAR AND ALSO THAT CERTAIN CLINICAL AND ESPECIALLY POST EXERCISE PARAMETERS ARE PREDICTIVE IN A CERTAIN DEGREE OF THE FATE UNSELECTED CASES WITH A WIDE RANGE OF CHEST COMPLAINS.
