Objectives:
to build and validate software for the care of people with cardiovascular risk.
Methods:
a methodological study, applied to software development, anchored in a nursing theory and classification system, in three stages: 1) requirements engineering; 2) software architecture and coding; and 3) testing and content validity by 12 experts in computer science, with a Content Validity Ratio score.
Results:
called e-TEORISC, in software format, for nursing care for people with cardiovascular risk, online and offline, containing a database linked to the Nursing Process stages. Experts considered that the attributes of functional suitability, performance efficiency, reliability, maintainability, usability, safety and portability obtained desirable scores.
Conclusions:
e-TEORISC has evidence of validity to instrumentalize care for people at cardiovascular risk, with potential for technology transfer to the Brazilian Health System.

Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
