Radiation exposure in different cardiac catheterization procedures in cath lab.

Background: Interventional procedures render cardiologolists and their team members to high doses of radiations. This study was conducted to assess the radiation exposure in various cardiac catheterization procedures.

Methods: This descriptive cross sectional study was conducted at the catheterization laboratory of Lady Reading Hospital Peshawar from November 2008 to December 2009.

Quantification of diagnostic accuracy using nitrate enhanced Tc-99m sestamibi gated myocardial SPECT in assessing myocardial viability: prospective analysis.

The aim of this prospective study was to assess myocardial viability with nitrate-enhanced Tc-99m sestamibi gated single-photon emission computed tomography in patients with known coronary artery disease. We enrolled 48 consecutive patients (39 men, 9 women) aged 24-82 years, with coronary artery disease and history of myocardial infarction. A Tc-99m sestamibi study was conducted at rest as baseline, followed by a nitrate-enhanced study the next day.

Prevalence of hypertension among obese and non-obese patients with coronary artery disease.

Background: Globally, obesity is now recognised as an epidemic. The degree of obesity is proportional to the rate of development of cardiovascular diseases, hence, resulting in a dramatic increase in morbidity and mortality. Apart from obesity, hypertension is another well recognised risk factor contributing to coronary artery disease (CAD).
