angina

main problem

heart is not getting enough oxygen for how hard it is working

oxygen supply is too low compared with oxygen demand

assessment

PQRTU

analysis

increase cardiac workload → heart needs more oxygen

decrease oxygen supply → heart muscle become ischemic

planning

nitroglycerin → reduces heart workload

rest → decrease oxygen demand

avoid trigger

implementation

monitor HR, BP, rhythm

EKG → heart electrical changes

troponin → check myocardial injury
