Table 3. Predictors of MACCE in the overall population by univariable and multivariable Cox regression analysis.
| Predictors of MACCE | Univariable analysis | Multivariable analysis | ||
|---|---|---|---|---|
| HR (95% CI) | p-value | HR (95% CI) | p-value | |
| Typical anginal symptoms during ACh provocation testing | 2.199 (1.129-4.281) | 0.020* | 0.921 (0.415-2.644) | 0.921 |
| Ischaemic ECG changes during ACh provocation testing | 2.270 (1.191-4.330) | 0.013* | 1.165 (0.474-2.861) | 0.739 |
| Epicardial coronary diameter reduction ≥90% | 2.775 (1.539-5.004) | 0.001* | 2.044 (1.064-3.924) | 0.032* |
| MINOCA as clinical presentation | 1.951 (1.132-3.363) | 0.016* | 1.892 (1.093-3.275) | 0.023* |
| Beta blocker therapy at discharge | 0.492 (0.253-0.958) | 0.037* | 0.601 (0.306-1.179) | 0.139 |
| CCB therapy at discharge | 2.585 (1.260-5.304) | 0.010* | 1.617 (0.700-3.735) | 0.261 |
| *Indicates statistical significance. All the characteristics shown in Table 1 were tested to predict MACCE at follow-up, although only variables with a p-value<0.05 have been shown in this table. Variables that were significantly (p<0.05) related to MACCE at follow-up on univariable Cox regression analysis were included in the multivariable Cox regression analysis. ACh: acetylcholine; CCB: calcium channel blocker; CI: confidence interval; ECG: electrocardiogram; HR: hazard ratio; MACCE: major adverse cardiovascular and cerebrovascular events; MINOCA: myocardial infarction with non-obstructive coronary arteries | ||||
