How would having a high blood pressure lead to cardiovascular disease?

Trauma. There are many theories to how elevated blood pressure leads to cvd. The most accepted theory is that of trauma and stress. Think of a fast running "high pressure" river... The banks of the river will feel more stress and accumulate more damage and irregularities over time than a slow creek. This same damage occurs to the vascular intima (or lining of our blood vessels) when exposed to high bp.
Several mechanisms. - damages blood vessels by harming cells lining them. - causes increased work/strain for heart muscle, causing it to enlarge (like any muscle that gets worked) ; over time, this process may result in impaired relaxation of heart (so it can't fill with blood) and dilation and weakening. High BP may cause hard/stiffening/narrowing of blood vessels (and thus not enough flow) also.

Absolutely. Hypertension just one, albeit important, risk factor in a plethora of identifiable risk factors that can contribute to heart disease. Lower bps are better, but not absolutely protective.

What medicines help heart disease and high blood pressure?

Meds to lower BP. Controlling BP with medications, especially beta blockers, ACE inhibitors, and diuretics will help to reduce risk of heart injury, heart failure and heart pain (angina). Some of the effects of high BP on the heart can be reversed with these BP meds and optimum control of BP (110-130/60-80). Follow up with primary MD and/or specialists (cardiologist and nephrologist if kidney problems). Read more...
