Comparison of chemical compounds and their influence on the taste of coffee depending on green beans storage conditions.

Currently, there is no technology for the storage of green coffee (GrC), that results in obtaining high-quality roasted coffee (RC). The aim of this study was to evaluate the effects of storage temperature (- 10, 5, 10, 18, 20 °C), postharvest treatment method (natural (N), washed (W)) and type of packaging material (GrainPro (G), jute (J) bags) on the content of chlorogenic acids (CQAs), caffeine and trigonelline as well as the sensory profile of RC from the specialty sector after 12 months of regulated storage. Sensory analysis showed that natural coffees have better taste and higher quality than washed coffees after 12 months of storage.

Borderline coronary lesions may lead to serious coronary events--long-term outcome in 65 conservatively treated patients.

Background: The choice of optimal therapy in a patient with borderline coronary lesion is difficult. The long-term outcome of conservatively treated patients has not yet been well defined.

Aim: To analyse long-term outcome in patients with a borderline lesion in a single coronary artery who were selected for conservative treatment.

Long-term outcome of conservatively treated patients with borderline coronary lesions--role of the fractional flow reserve measurement.

Background: Coronary fractional flow reserve (FFR) has been recommended as one of the functional methods which can be used to establish indications for revascularisation in patients with borderline coronary lesions.

Aim: To assess long-term outcome of patients with borderline coronary lesions in whom the decision to implement conservative treatment was based on the results of FFR.

Methods: The study group consisted of 41 patients (13 females, mean age 61+/-9 years) who had CCS class II angina, an isolated borderline (40-70%) coronary lesion and FFR >0.

Measurement of fractional flow reserve in patients with multi-vessel coronary artery disease and borderline lesions prevents unnecessary revascularisation procedures.

Background: Patients with multi-vessel coronary artery disease (CAD) are selected for percutaneous coronary interventions (PCI) or surgical revascularisation. The appropriateness of "ad hoc" PCI of borderline lesions (<70% of lumen diameter) in patients with a multi-vessel CAD has not been proven. However, delayed PCI of another lesion and gaining additional information from non-invasive tests is not a widely accepted strategy.
