下列哪項活動屬於三級預防？

預防醫學分為三級，三級預防（Tertiary prevention）的核心在於「疾病發生後的復健與併發症預防」。心臟復健計畫（Cardiac rehabilitation）旨在協助心肌梗塞後的病人恢復體能、改善生活習慣並防止再次發作，符合三級預防定義。血壓篩檢屬於二級預防（早期發現），疫苗接種與戒菸計畫屬於一級預防（預防疾病發生）。

Tertiary prevention focuses on rehabilitation and limiting disability after a disease event has occurred. Cardiac rehabilitation helps clients recover function and prevent complications following a myocardial infarction, whereas vaccination and smoking cessation are primary prevention, and screening is secondary prevention.
