At the cardiovascular level, this exposure elicits a range of acute and chronic adaptations, including activation of the sympathetic nervous system, pulmonary vasoconstriction, and vascular and ventricular remodelling. In the Andean region, millions of people live at elevations above 2,500 metres above sea level, rendering them particularly susceptible to these physiological adaptations and the associated cardiovascular alterations. This manuscript represents the first part of a narrative review and aims to synthesise the available scientific evidence on mechanisms of adaptation to high altitude, as well as the characteristics of pulmonary hypertension, heart failure, and congenital heart disease observed in both native high-altitude populations and individuals originating from low-altitude areas.

Its clinical recognition is challenging, as it may appear as an intermediate state in the evolution of cardiogenic or distributive shock, or result from the simultaneous coexistence of distinct pathophysiological mechanisms. Neurohormonal activation, which is common across both ends of the shock spectrum, contributes to fluid retention and further deterioration of circulatory function. Although pathophysiological interpretation is essential to guide management, it may be constrained by the temporal overlap of haemodynamic events. In clinical practice, the optimal approach integrates goal-directed haemodynamic correction with continuous bedside assessment of tissue perfusion. Pharmacological selection should account for the interaction between myocardial contractility and vascular tone, prioritising agents with combined or complementary effects.

Twenty studies published between 2019 and 2025 were analysed, highlighting alterations in left ventricular function (left ventricular ejection fraction [LVEF]), myocardial oedema detected by T2-weighted sequences, and fibrosis identified as late gadolinium enhancement (LGE). Key diagnostic criteria included elevated extracellular volume (ECV), impaired global longitudinal strain (GLS), and abnormal T1 and T2 relaxation times. Of the included studies, most were retrospective, followed by case reports and prospective studies. The therapies most frequently associated with ICI-M involved combinations of anti-PD1 and anti-CTLA4 agents. Cardiac magnetic resonance (CMR) has proven to be a highly sensitive, non-invasive tool for detecting myocardial involvement, even before the elevation of biomarkers such as troponins. The importance of using advanced tools like CMR to assess cardiovascular complications associated with myocarditis is highlighted.
