Posts Tagged ‘time window for unstable angina’

                                   ACS   is the  most common cardiac emergency .  Management of STEMI is relatively straight forward.  The  only decision that to be taken is the  modality of reperfusion. (Primary PCI   or thrombolysis.) There is no need to risk stratify  STEMI on arrival. All STEMI patients are considered high risk on admission. Whereas  NSTEMI consists of  a heterogeneous  population. They need to be   triaged into low intermediate  or high risk categorizes on arrival.There is two management  approaches for unstable angina .All high risk UA should enter early invasive strategy . And low risk and intermediate risk group will get early conservative management. 

                                       The principle of management of  UA differ from STEMI in a fundamental way , as there is no issue of myocardial salvage in UA .The primary aim is to provide relief from pain and prevent an MI. So in the strict sense there is no time window in unstable angina /NSTEMI.

 

                                       But it is generally considered 48 hours is the time limit for an early invasive approach.If the patient has crossed this time there is apparently no great difference in outcome for conservative and invasive approach.
