ABSTRACT
BACKGROUND: Pulmonary arterial hypertension (PAH) is an independent predictor of death in patients with human immunodeficiency virus (HIV) infection. HIV is the leading cause of PAH (HIV-PAH) worldwide. AIMS: We described the characteristics, treatment patterns, and prognosis of a cohort of HIV-PAH patients and compared them with those of an equivalent cohort of patients with idiopathic/familial PAH (IPAH/FPAH). METHODS: We retrospectively analysed and compared the demographic, clinical, and treatment data from patients with HIV-PAH and those with IPAH/FPAH in the Spanish PAH registry (REHAP) from 1998 to 2018. The HIV-PAH overall survival (OS) rate up to 5 years was compared to the age- and sex-matched IPAH/FPAH population. Changes in treatment patterns in patients with HIV-PAH after 2010 and their effects on OS were also analysed. RESULTS: Compared to those with IPAH/FPAH (n = 739), patients with HIV-PAH (n = 132) were younger, mainly men, and had a better functional status. The clinical presentation, haemodynamics, and respiratory function were similar between the groups. Parenteral drug use was the most common mode of HIV transmission. Approximately 11% of patients with HIV-PAH did not receive PAH-targeted therapy. The age- and sex-adjusted 5-year OS rate from diagnosis was 74.0% for patients with HIV-PAH and 68.7% for those with IPAH (p < 0.159). During/after 2010, 23% of patients with IPAH/FPAH received upfront dual oral combination, while oral monotherapy remained the main first-line treatment in patients with HIV-PAH. The overall OS rate remained stable. CONCLUSIONS: Patients with HIV-PAH were predominantly young men. The short-term prognosis is similar to that of age- and sex-matched patients with IPAH/FPAH, despite a better functional status. Oral monotherapy remains the preferred first-line treatment in the current cohorts.

BACKGROUND: Pulmonary arterial hypertension (PAH) is common in patients with congenital heart disease (CHD). Although Eisenmenger syndrome may be on decline, other types of PAH-CHD are increasing and little is known on long-term outcome of this population. We report the PAH-CHD population of Spain via a national registry with focus on long-term survival. METHODS AND RESULTS: A total of 240 consecutive patients (age 37.7 ± 14.1 years, 67.9% females) with PAH-CHD included in the REHAP registry were analysed. Patients were classified into 3 groups: 1) Eisenmenger syndrome, 2) postoperative-PAH and 3) PAH associated with small defects. Over a median follow-up time of 4.5[1.6-7.1]years, 50 patients (20.8%) died or underwent lung/heart-lung transplantation. Patients with Eisenmenger syndrome had better survival than postoperative-PAH (HR 0.1 95% CI: 0.2-0.9, p=0.048) but no advantage compared to small defects (HR 4.4, 95% CI 0.6-31.4, p=0.15). In the overall PAH-CHD population, patients in NYHA functional class III-IV had a 3-fold increased risk of death (HR 3.0, 95% CI: 1.5-5.9, p=0.001). Amongst patients with Eisenmenger syndrome, a pre-tricuspid shunt had a 2.6-fold increase risk of death (HR 2.6, 95% CI: 1.2-5.6, p=0.03). There was no significant difference in survival between patients with postoperative-PAH and patients with iPAH (HR 0.99 95% CI: 0.6-1.7, p=0.97). CONCLUSION: PAH-CHD is associated with mid to long-term mortality. Outcome relates closely to functional class, type of PAH-CHD and within the Eisenmenger cohort, with location of the shunt. Adults with postoperative-PAH have the worse prognosis in the PAH-CHD cohort, reinforcing the need for lifelong close follow-up of such patients.

Los casos de isquemia miocárdica demostrada debida a la presencia de fístulas coronarias múltiples son escasos. Presentamos un caso de fístulas coronarias múltiples dependientes de la descendente anterior, arteria circunfleja y coronaria derecha, con drenaje en el ventrículo izquierdo, responsables de isquemia demostrada mediante ergometría con talio. El diagnóstico fue angiográfico y su etiología congénita. El control definitivo de los síntomas se consiguió con betabloqueantes y no con nitratos, en consonancia con el fenómeno de robo coronario como causante de la isquemia (AU)
