The massive rate of CHD in former Soviet states is attributable to many things - industrial and agricultural pollution, smoking and alcohol, untreated chronic infections, overwork, malnutrition, higher birthrate, lower incomes (the US CHD rate in 2008 was 126 per 100,000 - this is both sexes, age adjusted, so not exactly comparable to Dr Kendrick's table; see here for more age-adjusted data and discussion). To look at the correlations between these things and CHD is enough to question the existence of any diet-heart link whatsoever. What significance does a RR of 1.17 have in a world where RRs of 11.13 exist?
If, however, we must look at these statistics in diet-heart terms, one thing stands out to this student of history. Russia is the world's oldest producer, and consumer of vegetable seed oils. The sunflower was brought to Europe by the Spanish around 1510, and were established in the Netherlands (then part of the Spanish Empire) soon after. Peter the Great then brought the sunflower to Russia after his visit to the Netherlands in 1698. In 1716 a patent was granted in Great Britain for a method of extracting oil from sunflower seeds, and during the 1840s the Tsarist government of Russia began the manufacture of sunflower oil on an industrial scale.
Because the Lent restrictions of the Russian Orthodox Church forbade the consumption of fat, this seemed like a good idea at the time (once again the ascetic impulse will be the driver for a dietary change later to be justified and entrenched by theories about health).
The Great Soviet Encyclopaedia of 1979 naturally downplays the Tsarist achievement.
And so on - the communist love of boring statistics was useful after all.
But wait - there's more. If the Tsars boosted the seed oil industry, the Bolsheviks, for political reasons, destroyed whatever dairy industry there was in Russia during their genocidal campaign against the "kulaks", which they defined as any farmer rich enough to own a cow, plus anyone they didn't like or who opposed their seizures of food, summary executions, and so on.
To destroy the dairy farmers they needed a substitute - so Soviet Russia, beginning in the 1920s, became the first large scale producer of soy products. The USSR was the first nation in Europe and the second nation in the Western world (after the USA) to become a major producer of soybeans. Soybean production, which reached significant levels in the mid-1920s, rose to a remarkable peak of 283,000 tonnes in 1931, but had fallen back to a low of 54,000 tonnes in 1935, after which it increased steadily. At the time of this peak, starting in 1931, the USSR built a large Soybean Research Institute in Moscow, attracted some of the top soybean and soyfoods researchers from western Europe (Rouest, Berczeller), and did extensive soyfoods research, focusing on soymilk and tofu, during the early 1930s.
So by any utopian diet-heart, lipid hypothesis theory of history, those former Soviet states should have had CDH beat years ago.
By the test of reality, on the other hand, you would be better off living in France on butter, cheese, cream and, hey, if you like it why not, olive oil.
