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 Eurasian Steppe extends thousands of miles from near the mouth of the Danube River almost to the Pacific Ocean. It is bounded on the north by the forests of Russia and Siberia. There is no clear southern boundary although the land becomes increasingly dry as one moves south. The steppe narrows at two points, dividing it into three major parts.
