[Cardiology in 1997].
A review of the most important findings published during 1997 in cardiovascular papers is presented: Chlamydia pneumoniae was recognised as a potential risk factor for coronary artery disease (CAD) and possible pathogenic agent for valvular aortic stenosis. Valvular changes similar to the valvular disease reported after ergotamine and methylsergide were also detected in obese women treated with a combination of phentermine and fenfluramine. In CAD, several new laboratory methods were introduced for early diagnosis, such as serum troponin levels, and arbutamine and adenosine stress echocardiography. Laser transmyocardial revascularisation can be performed in patients unsuitable for PTCA and CABG. In patients with end-stage heart failure, implantable ventricular-assist devices can be used, and dynamic cardiomyoplasty or partial ventriculectomy may be useful temporary measures until a suitable heart donor is available. In pharmacotherapy, fluvastatin was registered as an antiatherosclerotic agent, and mibefradil and moxonidin in hypertension and angina. Digoxin was shown to reduce the number of hospitalisations in patients with CHF but still in sinus rhythm. In the future, several improvements in anti-thrombotic therapy are expected: antithrombins, platelet glycoprotein IIb/IIIa receptor blockers and tissue factor inhibitors are all potentially more potent than presently available drugs. Also, efforts are under way to introduce genes directly into the cells of the vascular wall to prevent atherosclerosis and restenosis, as well as to transform cardiac mesenchymal cells into the cardiac myocytes of hearts that have suffered large infarctions.
