Estimates of Prevalence of Pulmonary Hypertension according to Different International Definitions

Table 4

Prevalence and severity of pulmonary hypertension (mPAP ≥ 20 mmHg).

S. no.	Severity of pulmonary hypertension	Number of patients	Percentage	Female (n = 141)		Male (n = 98)
				No.	%	No.	%
1	No pulmonary hypertension	129	54.0	72	55.8	57	44.2
2	Mild pulmonary hypertension	80	33.5	52	65.0	28	35.0
3	Moderate pulmonary hypertension	28	11.7	17	60.7	11	39.3
4	Severe pulmonary hypertension	2	0.8	0	0.0	2	100.0

χ² = 4.644 (df = 3); ; χ² = 1.173 (df = 1); (for no pulmonary hypertension (n = 129) vs. pulmonary hypertension (n = 110)). mPAP, mean pulmonary artery pressure; df, degrees of freedom.
