Table 2 Differential diagnosis between TTS and Complications after PCI.

Symptoms

heart failure is the primary symptom. Chest tightness can occur, but it is usually mild, with less chest pain, nausea, and vomiting.

Severe chest pain, chest tightness, palpitations, nausea, and vomiting are common symptoms.

ECG

ECG shows ST segment elevation or T wave alterations that surpass the blood supply area of a single artery and changes dynamically as the disease progresses.

ST-T changes in the leads

corresponding to the occluded vessel’s blood supply area, which changes dynamically as the disease progresses.

Echocardiography

The extent of ventricular wall motion abnormalities usually exceeds the area supplied by a single coronary artery,accompanied by abnormal myocardial perfusion.

The extent of ventricular wall motion abnormalities usually corresponds to the area supplied by a single coronary artery.

CMR

The aberrant range of ventricular wall motion typically surpasses the area dominated by a single coronary artery, and the severity of local myocardial edema, perfusion deficiency, and delayed enhancement varies significantly.

The area dominated by a single coronary artery usually corresponds to the aberrant range of ventricular wall motion. Local myocardial edema, perfusion deficit, and delayed enhancement are usually significant.

Operation

The intervention went without a hitch.

There may be factors such as the formation of vascular wall dissection, poor stent attachment, and tissue prolapse during the intervention.

Coronary angiograms

All 3 coronary arteries are smooth and the blood flow is unobstructed, no thrombus shadow and no contrast agent retention.

Vascular occlusion, thrombosis and contrast agent retention may be seen.
