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).
Desert: a region with so little vegetation that no significant population can be supported on that land. This implies that it is dry, but not necessarily hot. There are several kinds of deserts, but they all have one thing in common - they each receive less than 25 cm (~10) of precipitation per year. Polar ice and snow deserts - the cold climate produces both low precipitation and relatively high evaporation rates, e.g., Antarctica.
