Contrast stress echocardiography in hypertensive heart disease
Hypertension is associated with atherosclerosis and cardiac and vascular structural and functional changes. Myocardial ischemia may arise in hypertension independent of coronary artery disease through an interaction between several pathophysiological mechanisms, including left ventricular hypertrophy, increased arterial stiffness and reduced coronary flow reserve associated with microvascular disease and endothelial dysfunction. The present case report demonstrates how contrast stress echocardiography can be used to diagnose myocardial ischemia in a hypertensive patient with angina pectoris but without significant obstructive coronary artery disease. The myocardial ischemia was due to severe resistant hypertension complicated with concentric left ventricular hypertrophy and increased arterial stiffness
Heart Angiotensin-Converting Enzyme and Angiotensin-Converting Enzyme 2 Gene Expression Associated With Male Sex and Salt-Sensitive Hypertension in the Dahl Rat
Angiotensin-converting enzyme 2 (ACE 2) in the heart including its sex dependency in the hypertensive heart, has not been much studied compared to ACE. In the present study, we used the Dahl salt-sensitive rat exposed to fructose and salt to model a hypertensive phenotype in males, females, and ovariectomized females. Blood pressure was measured by the tale-cuff technique in the conscious state. Expression of RAS-related genes ACE, ACE2, angiotensin II receptor type 1, Mas1, and CMA1 in the heart were quantified. The results revealed small but significant differences between male and female groups. The main results indicate the presence of a male preponderance for an increase in ACE and ACE2 gene expression. The results are in accordance with the role of androgens or male chromosomal complement in controlling the expression of the two ACE genes
Supporting Self-managed Abortion Care in “practice not premise”: Provider Perspectives, Roles, and Referral Pathways in India
Objective: Describe provider perspectives and roles in self-managed abortion (SMA) in India and identify referral pathways to facility- and self-managed abortion care.
Methods: We conducted a qualitative study of 33 semi-structured interviews with a range of providers (medical, community health, and pharmacy) in India. We conducted a thematic analysis and identified referral pathways including the type of provider, the abortion care modality (in-facility or SMA), and the reason.
Results: Referrals to facility-managed abortion care were common. Providers\u27 perception of SMA safety coupled with liability concerns resulted in discouraging clients from seeking SMA. Nonetheless, participants acknowledged three areas where providers played a role in SMA: providing information, dispensing medication, and providing support. SMA referrals pathways occurred bidirectionally between pharmacy workers and local providers. Some community health workers provided referrals to pharmacies, but more often only provided information and support.
Conclusion: Despite provider concerns, support and referrals for SMA do occur in India. Understanding the dynamics of provider perspectives, roles, and referral pathways can inform improvements to comprehensive reproductive health policies and programs in order to promote client-centered abortion care—including SMA—and address provider concerns. There is a need for synergies between the formal health sector and SMA support networks.
