What is diabetic heart disease? are dizziness, shortness of breath, cold tips of finders and chest pain strong indicatros of diabetic heart disease?

All : All of these can be symptoms of cardiology, and diabetes dramatically increases the risk of cardiology. Chest pain, shortness of breath, and associated dizziness can all be symptoms of angina, which is caused by narrowing or blockages in the coronary arteries. Angina might also be accompanied by excessive sweating, nausea, or fatigue. Cold finger tips may be a symptom of poor circulation to the hands, which can be caused by atherosclerosis in the peripheral arties or also by diabetic nerve disease. If you have these symptoms, whether or not you have diabetes, you should definitely see your doctor for further evaluation.

No such thing: There isn't actually such an entity per se but people with diabetes tend to develop accelerated atherosclerosis which tends to affect the smaller (distal) vessels to a greater extent than non-diabetics. That could result in angina (chest pain)but often doesn't because diabetics lose the ability to perceive pain. Dizziness and cold fingers are non-specific issues caused by many things.

Have it evaluated: A person with chest pain needs to be evaluated and treated appropriately. Multiple possible causes may be: heart attack, esophageal reflux, anxiety, musculoskeletal, pneumonia, pulmonary embolus, and aortic dissection. Have it evaluated right away to prevent potential serious complications.
