Judging by the following quotes, it appears you are uninformed.
Quoting from the American Heart Association:

Also, moving back and forth between cold water baths and saunas or hot tubs can raise blood
pressure. If you have high blood pressure, don't do this.
Quoting from the Finnish Sauna Society:
http://www.sauna.fi/pages/traditi.htm
A very rapid change from the hot into the icecold can be too strenuous even to a healthy person and
is not recommended, it is better to let the pulse settle for a while before a dip in the water or
snow. People with heart problems should stay away from this kind of cooling off completely.
Quoting from this abstract on Medline:

The results demonstrated decreased total peripheral resistance (TPR) to the blood flow in response
to the heat of the sauna (C), with concurrent increase in cardiac oxygen demand and negligible
increase in the stroke work. Cold exposures (D) increased the TPR. Cold did not increase the cardiac
oxygen demand but increased the stroke work. The alternation of heat and cold (A) or cool (B)
presented the most intensive strain on the heart.
