Hypertensive heart disease. Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart. While there are several definitions of hypertensive heart disease in the medical literature, the term is most widely used in the context of the International Classification of Diseases (ICD) coding categories.
History of the Steppe Introduction Geography. The Steppe (aka the Eurasian Steppe) is a vast strip of land stretching from Ukraine to Mongolia. The term steppe denotes grassland: a low-precipitation region with enough rain for grass, but not enough for trees (see Climates and Biomes).
The North and South American prairies and the Asian and Australian steppes are grassland habitats that, unlike the savanna, undergo greater changes in season and temperature: hot in the summer and cold in the winter.
