Abstract.
Clinical and laboratory findings of 42 patients with High Altitude Polycythemia were analyzed consecutively.
All patients had hemoglobin (Hb) and hematocrit (Ht) levels above 19 g/dl and 60%, respectively.
Patients with obesity and/or cardiorespiratory disease were excluded from the study. All lung function tests were normal.
The patients were divided in 2 groups: group A: 11 Patients under 35 years; group B: 31 patients above 35 years.
These 2 groups were compared to each other.
The results show that High Altitude Polycythemia is a clinical condition in high altitude natives, even in young adults in whom 2 important risk factors are residence at altitudes of 4000 m and moderate overweight.
A great variety of clinical findings is present in relation to cardiorespiratory, hematological and neurological symptoms.
Alterations of EKG, chest X ray and echocardiogram are characterized by overload of the right chambers.
