TL;DR: This study sought to investigate whether spironolactone protects the heart against anthracycline‐induced cardiotoxicity and found it safe and effective.
Abstract: Aims
The protective effect of beta-blockers, ACE inhibitors, and ARBs on anthracycline cardiotoxicity has already been demonstrated, but the effect of aldosterone antagonism, which inhibits the last step of the renin–angiotensin–aldosterone system (RAAS), was questioned. This study sought to investigate whether spironolactone protects the heart against anthracycline-induced cardiotoxicity.
Methods and results
Eighty-three female patients who were diagnosed with breast cancer were included in the study. The study population was randomized into spironolactone and control groups. A dose of 25 mg/day spironolactone was administered to the patients in the spironolactone group. There were 43 patients (mean age 50 ± 11 years) in the spironolactone group and 40 patients (mean age 51 ± 10 years) in the control group. LVEF decreased from 67.0 ± 6.1 to 65.7 ± 7.4 (P = 0.094) in the spironolactone group, and from 67.7 ± 6.3 to 53.6 ± 6.8 in the control group (P < 0.001). When the general linear model was applied, the interaction of LVEF decrease between groups was significantly lower in the spironolactone group than in the control group (P < 0.001). The diastolic functional grade of subjects in the spironolactone group was protected (P = 0.096), whereas it deteriorated in the control group (P < 0.001).
Conclusion
We showed that spironolactone administration used simultaneously with anthracycline group chemotherapeutics protects both myocardial systolic and diastolic functions. Spironolactone can be used to protect against anthracycline-induced cardiotoxicity.

TL;DR: Despite normal coronary arteries, myocardial dysfunction may occur in patients with CO poisoning, and LV systolic function might be normal or mildly to severely impaired.
Abstract: Carbon monoxide (CO) poisoning is an important health problem Cardiac abnormalities may occur in patients with CO poisoning; however, the severity and duration of cardiac abnormalities are not well known In this study, cardiac structures and function in CO poisoning were evaluated prospectively Twenty patients were enrolled in the study Echocardiographic examination was performed in all patients on admission, at 24 hours, and within the first week B-type natriuretic peptide and carboxyhemoglobin levels were measured Patients with increased cardiac markers underwent coronary angiography Cardiac markers were high in 6 patients Patients with high cardiac markers had significantly higher carboxyhemoglobin levels and longer exposure to CO Left ventricular ejection fraction (LVEF) was 55% in 7 patients in group I 24 hours after echocardiography A significant negative correlation was found between B-type natriuretic peptide and LVEF on admission (r = -0586, p <001) The decrease in LVEF was also negatively correlated with carboxyhemoglobin level and CO exposure duration All angiograms showed normal coronary arteries In conclusion, despite normal coronary arteries, myocardial dysfunction may occur in patients with CO poisoning LV systolic function might be normal or mildly to severely impaired However, most of the myocardial dysfunction dissipates at 24 hours in patients with CO poisoning

TL;DR: Long-term and high-dose allopurinol therapy significantly improved endothelial function in diabetic normotensive patients and contributes to the lower HbA1c levels.
Abstract: Objectives. Endothelial dysfunction is a well known risk factor for atherosclerosis. Uric acid levels are associated with endothelial dysfunction and atherosclerosis even if in physiological range. Xanthine oxidase inhibition with allopurinol decreases uric acid levels and oxidative stress and improves endothelial function. We have investigated the effect of high-dose and long-term allopurinol therapy on endothelial function in diabetic normotensive patients. Methods. This study is a randomized, single-blind, placebo-controlled trial. Both treatment and placebo groups consisted of 50 patients. In the treatment group, daily oral 900 mg allopurinol was started after randomization and maintained for 12 weeks. Brachial artery flow-mediated dilatation (FMD) and nitrate-induced dilatation (NID) were measured at baseline and after the allopurinol therapy to evaluate endothelial function. Results. HbA1c and uric acid levels decreased after allopurinol therapy (6.1 ± 2.1 vs 5.5 ± 1.0%, 5.0 ± 0.8 vs 3.3 ± 0...

TL;DR: It is concluded that early diastolic mitral annular and myocardial velocities are affected by acute preload reduction.
Abstract: Doppler tissue imaging (DTI) has been proposed as a tool for the evaluation of diastolic function. Controversy exists regarding whether DTI measurements are influenced by preload. Changes in the circulating volume associated with hemodialysis result in preload reduction. To determine the influence of preload reduction on DTI and standard pulsed-Doppler transmitral diastolic velocities, 30 patients (mean age 41 +/- 14) with chronic renal insufficiency without overt heart disease were studied by DTI and standard pulsed Doppler before and after hemodialysis. From the apical window, DTI sample volume was placed at the lateral and septal mitral annulus and at the midsegment of lateral and septal myocardial wall of the left ventricle. Peak early diastolic annular and myocardial, and peak late diastolic annular and myocardial velocities were measured. Transmitral peak early and late diastolic velocities were also recorded by standard pulsed Doppler. The peak velocity of early diastolic mitral flow decreased from 100 +/- 30 to 85 +/- 34 cm/s (P < 0.001) after hemodialysis. Hemodialysis elicited marked reduction in early diastolic lateral mitral annular and midlateral myocardial velocities (6.9 +/- 3.2 to 6.3 +/- 2.9 cm/s, P < 0.04 and 6.7 +/- 0.3 to 5.5 +/- 2 cm/s, P < 0.001, respectively). Early diastolic, septal mitral annular, and midseptal myocardial velocities were also significantly decreased (5.8 +/- 2.8 to 4.6 +/- 2 cm/s, P < 0.006 and 6.2 +/- 2 to 5.1 +/- 1 cm/s, P < 0.008, respectively). Late diastolic mitral annular and myocardial velocities did not change. It is concluded that early diastolic mitral annular and myocardial velocities are affected by acute preload reduction. It is necessary to consider preload when diastolic function is assessed by DTI.

TL;DR: 2007 Guidelines for the Management of Arterial Hypertension : The Task Force for the management of Arterspertension of the European Society ofhypertension (ESH) and of theEuropean Society of Cardiology (ESC).
Abstract: Because of new evidence on several diagnostic and therapeutic aspects of hypertension, the present guidelines differ in many respects from the previous ones. Some of the most important differences are listed below:
1. Epidemiological data on hypertension and BP control in Europe.
2. Strengthening of the prognostic value of home blood pressure monitoring (HBPM) and of its role for diagnosis and management of hypertension, next to ambulatory blood pressure monitoring (ABPM).
3. Update of the prognostic significance of night-time BP, white-coat hypertension and masked hypertension.
4. Re-emphasis on integration of BP, cardiovascular (CV) risk factors, asymptomatic organ damage (OD) and clinical complications for total CV risk assessment.
5. Update of the prognostic significance of asymptomatic OD, including heart, blood vessels, kidney, eye and brain.
6. Reconsideration of the risk of overweight and target body mass index (BMI) in hypertension.
7. Hypertension in young people.
8. Initiation of antihypertensive treatment. More evidence-based criteria and no drug treatment of high normal BP.
9. Target BP for treatment. More evidence-based criteria and unified target systolic blood pressure (SBP) (<140 mmHg) in both higher and lower CV risk patients.
10. Liberal approach to initial monotherapy, without any all-ranking purpose.
11. Revised schema for priorital two-drug combinations.
12. New therapeutic algorithms for achieving target BP.
13. Extended section on therapeutic strategies in special conditions.
14. Revised recommendations on treatment of hypertension in the elderly.
15. Drug treatment of octogenarians.
16. Special attention to resistant hypertension and new treatment approaches.
17. Increased attention to OD-guided therapy.
18. New approaches to chronic management of hypertensive disease
