 DEFINITION AND METHODS OF ASSESSMENT TEST DELLHANDGRIP HGT. The handgrip test measures the force of contraction of the flexor muscles of the fingers through the use of a dynamometer. From literature it is known as such index correlates with the eventual malnutrition of the subject, with its capacity of recovery and functional recovery post-surgery, as well as to be in relation with age. The measurement will be made at the time of admission, namely within 24 hours of admission in acute coronary care in the event that the patient is admitted with a diagnosis of acute myocardial infarction with ST-segment elevation or before being subjected to coronary angiography in case aortic valve disease or acute coronary syndrome without ST-segment elevation, under the supervision and assistance of medical staff. In each patient, three measurements will be carried out. Will be taken into consideration for the study the highest value. The measurement will be performed as indicated by current guidelines, with the patient seated, with the dominant hand and the elbow flexed 90. They are well known limitations of the method and its variability. At the same time this method was chosen because it is not laborious, virtually cost-free, well-administered in all patients admitted for ACS or aortic valve disease and therefore readily identifiable as a method of coarse screening in elderly patients without known diagnosis of frail elderly but at risk to be. All medical personnel involved in the study performed a specific course to learn the proper management and execution of screening with handgrip tes and has personal experience in its proper execution.
