Cardiac Adverse Reactions Related to Immune Checkpoint Inhibitor in NSCLC Patients

This is a prospective, open label, single arm study. A total of 300 patients with primary non-small cell lung cancer treated with PD-1/PD-L1 immune checkpoint inhibitors(ICIs) are expected to included . All patients will follow up for at least 1 year. Patients with cardiac adverse reactions after PD-1/PD-L1 immune checkpoint inhibitor treatment at admission or during the subsequently follow-up period will randomly assigned a random number to each patient by computer random sequence. Patients with odd random number will treat with RASI（renin-angiotensin system inhibitors）, and those with even random number will treat with ARNI（angiotensin-receptor-neprilysin inhibitor）.
